A spokesman for Ohio State University says a suspect in an attack on campus that injured at least eight people has been shot and killed.

Ben Johnson also said Monday that injuries in the attack included stab wounds and being struck by a vehicle.

A law enforcement official told The Associated Press that the suspect is believed to have initially struck people with a car before beginning to stab victims. There was no indication that the suspect shot anyone. The official wasn't authorized to discuss an ongoing investigation by name and spoke on condition of anonymity.

The details started to emerge after a morning of confusion and conflicting reports that began with the university issuing tweets warning students that there was an "active shooter" on campus near the engineering building and that they should "run, hide, fight."

COLUMBUS, Ohio (AP) — Eight people were sent to hospitals Monday morning with non-life-threatening injuries after an attack on the Ohio State University campus, fire and hospital officials said after the school sent a series of tweets telling students to shelter in place and to "Run Hide Fight."

Some of the victims had been stabbed and others were hit by a vehicle, said Ben Johnson, a university spokesman. Some of the other injuries were being evaluated, he said.

"Our top priority remains the safety and security of our campus community," he said.

The eight patients were split among OSU Wexner Medical Center, OhioHealth Grant Medical Center and OhioHealth Riverside Methodist Hospital.

Cassidie Baker, an Ohio State senior, said she saw police or paramedics helping one person on the ground outside Watts Hall.

"No one really knows what is happening, other than there's an active shooter," she said.

Ohio State said about an hour and a half after sending out a series of tweets about an active shooter on campus that a shelter-in-place warning had been lifted and the scene was secure. The university tweeted that all classes would be canceled for the rest of the day.

Around 10 a.m., the university's emergency management department tweeted "Buckeye Alert: Active Shooter on campus. Run Hide Fight. Watts Hall. 19th and College." Watts Hall is a materials science and engineering building.

"Run, hide, fight" is standard protocol for active shooter situations. It means: Run, evacuate if possible; hide, get silently out of view; or fight, as a last resort, take action to disrupt or incapacitate the shooter if your life is in imminent danger.

The university followed up with another tweet: "Continue to shelter in place in north campus area. Follow directions of Police on scene." The university asked for anyone with information to call police.

Many police vehicles were at the scene. Police also blocked off roads around the perimeter of the campus, clogging area traffic.

An active shooter has been reported on Ohio State University’s campus, with at least seven people taken to the hospital, according to the authorities. It is not clear the conditions of the victims or the severity of the injuries.

People are urged to take shelter and to avoid the area.

OSU Emergency Management tweeted this morning, “Buckeye Alert: Active Shooter on campus. Run Hide Fight. Watts Hall. 19th and College.”

Anthony Falzarano, 22-year-old senior was in class the time of the shooting.

“We heard a lot of sirens. I was in class and everyone got a text message at the same time for the emergency alert,” he told CNN. “Someone said they heard popping right before we got the alert, but I didn’t hear it. We are in a shelter-in-place right now in the building next door. ”

Wyatt Crosher, 19-year-old sophomore said, “”My roommate and I heard about three or four gunshots from across the street, and soon after we heard a bunch of police and ambulances pull up across the street.”

Students were removed from the scene as police continue to investigate.

“As you may have heard, our friends at The Ohio State University are experiencing an active shooter on their campus,” WSU president David Hopkins released in an e-mail statement. “Please keep them in your thoughts as we watch these events unfold. Also, please be ever vigilant about your own environment. We will keep you updated with any information you may need for your own safety. And please visit http://www.wright.edu/police/emergency-preparedness to familiarize yourself with our emergency procedures.”</s>Police respond to reports of an active shooter on campus at Ohio State University in Columbus, Ohio on Monday

A shooting at Ohio State University sent seven people to the hospital Monday morning, the Columbus Fire Department said shortly after the school sent a series of tweets telling students to shelter in place and to “Run Hide Fight.”

Two of those people are in stable condition, the department said. It had no information on the other five people. It was not immediately clear whether the shooting was still in progress.

Investigators are examining Abdul Razak Ali Artan's Facebook page to determine whether the attack was terrorism, though law enforcement officials said it will take time to ascertain motive.

In a Facebook post shortly before the Monday morning rampage, the Somali immigrant urged America "to stop interfering with other countries, especially the Muslim Ummah," a term for Muslim people at large.

"By Allah, we will not let you sleep unless you give peace to the Muslims. You will not celebrate or enjoy any holiday."

Artan rammed his car into a group of people on the Columbus campus before exiting the car and charged at others with a knife. Eleven people were hospitalized as a result of the attack.

Ohio State Police Officer Alan Horujko shot Artan after he failed to obey orders to stop.

Authorities investigate the scene of the attack, where the assailant struck people with his vehicle and then cut them with a butcher knife.

In a news conference Monday, Ohio State President Dr. Michael V. Drake cautioned against jumping to conclusions when asked if the incident was terror-related or had anything to do with Ohio's Somali community, the second-largest in the country.

"We all know when things like this happen that there's a tendency sometimes for people to put people together and create other kinds of theories. We don't know anything that would link this to any community. We certainly don't have any evidence that would say that's the case," Drake said.

"What we want to do is really unify together and support each other; do our best to support those who were injured in their recovery, and then allow the investigation to take place."

What we know about the attacker

Artan was profiled in the school's student-run newspaper 's "Humans of Ohio State" series in August. He had just transferred from Columbus State and said he was struggling to find a place to pray in peace on the large campus.

"I wanted to pray in the open, but I was scared with everything going on in the media. I'm a Muslim, it's not what the media portrays me to be. If people look at me, a Muslim praying, I don't know what they're going to think, what's going to happen.

Abdul Razak Ali Artan

A community member who spoke to the attacker's family described them as shocked. The community member described Artan as a good kid. She confirmed Artan had just finished community college before starting this semester at Ohio State.

Artan was a legal permanent resident originally from Somalia, a US official said. He came to the country in 2014 with his family via Pakistan, a federal law enforcement official and a US official told CNN.

Artan left Somalia in 2007 with his family for Pakistan and they were admitted as refugees as part of a minority sect of Somalis, a senior administration official told CNN. Seven members of the family applied for refugee status in the United States and were admitted in 2014. Today, they are all legal permanent residents and green card holders.

Neighbor Stephanie Leper told CNN Artan's family occupies four units. Law enforcement vehicles arrived at the town homes sometime after 10 a.m. and took people away in "paddy wagons," she said.

Artan said reports of human rights abuses in Myanmar pushed him to a "boiling point." The United States, which suspended its last sanctions against the former military dictatorship this year, said it had expressed concerns about the treatment of Myanmar's Rohingya Muslims.

"I can't take it anymore," he said in the post.

How it happened

Artan's rampage ended in less than two minutes thanks to Officer Horujko's quick response, officials said.

"We owe him a debt of gratitude," said Monica Moll, director of Ohio State public safety. "He did a fabulous job today."

At 9:52 a.m., he drove over a curb and struck people near Watts Hall.

Horujko called in the car at 9:52 a.m. A few seconds later, he called in to say he had engaged with the suspect. At 9:53 a.m., he radioed in again to say he had shot the suspect.

Student Jacob Bower, 20, said he saw the attacker outside between the Koffolt Laboratories and Watts Hall.

"He pulled a large knife and started chasing people around, trying to attack them," Bower told CNN, adding that he did not see anyone get stabbed.

"Luckily there were so many people, he couldn't focus on one target," he said.

It took Horujko three shots to take Artan down, Bower said.

"He waited 'til everyone was clear, and the stabber clearly wasn't stopping."

Throughout the attack, the assailant didn't yell or say anything, Bower said.

"He was completely silent, which was very creepy. Not even when he was shot," the student said.

"The cop that subdued the guy with the knife saved so many lives today."

Investigators used surveillance camera footage to track Artan's car before he arrived on campus, University Police Chief Craig Stone said. By tracing his movements, investigators were able to conclude he was alone in the vehicle and acted alone.

Gov. John Kasich praised the response, saying it showed "how much practice, how much training, how much expertise, how much coordination" existed among local law enforcement agencies.

"We are a strong, tough, resilient community," he said.

'Run, hide, fight'

Drake and others credited the school's active shooter training and the campus alert system for helping the community maintain order while the scene was secured. Ohio State's Columbus campus is one of the largest in the United States, with 59,482 registered students attending classes on the sprawling urban campus.

At 9:55 a.m., the school sent out a campus alert reporting an active shooter incident.

"Buckeye Alert: Active Shooter on campus. Run Hide Fight . Watts Hall. 19th and College," Ohio State Emergency Management tweeted at 9:56 a.m.

While students waited to hear word on the attacker's movements, some piled chairs against a door to block him from getting in.

Ohio State students barricade themselves to try to stay safe from the attacker.

"I'm safe in a barricaded room," Harrison Roth tweeted . "If you're on campus, get in a room and stay safe."

In 911 calls to police, several students described the chaotic scene.

"I think this is some type of terrorist attack," said one caller, according to CNN affiliate WCMH . "Because the guy ran a car through a crowd of students. The guy did it purposefully."

About 90 minutes after the first call came in, the lockdown was lifted, Drake said.

Students had just returned to class Monday after the Thanksgiving break -- and after the OSU football team's big win Saturday over the school's biggest rival, the University of Michigan.

Abdul Razak Ali Artan was shot and killed within minutes after plowing into the group by a police officer with less than two years on the force, said Monica Moll, director of public safety for Ohio State University.

"It frankly took a piece out of everybody here at our beautiful Ohio State University that this could have happened here," Ohio Governor John Kasich said at a news conference.

A U.S. government official confirmed the assailant was from Somalia, 18 years old and a lawful permanent resident of the United States. A second government source said investigators had reason to believe the attacker at the campus in Columbus was a Somali refugee. Columbus, the state capital, has a large Somali population.

U.S. Congressman Adam Schiff, a California Democrat and the ranking member of the House Permanent Select Committee on Intelligence, said intelligence agencies were assisting in the investigation.

"It bears the all of the hallmarks of a terror attack carried out by someone who may have been self-radicalized," Schiff said in a statement.

Another U.S. official told Reuters U.S. agencies are investigating the Columbus attacker's background and motivations, but cannot clearly say yet whether he had any ties to suspected militant cells or groups.

The attack at the Columbus campus, which was initially reported by the university on Twitter as involving an "active shooter," drew a massive response of heavily armed police.

The suspect jumped the curb and used the vehicle to strike pedestrians in front of Watts Hall, Moll said.

The suspect left the vehicle armed with the knife and stabbed several others, Ohio State University Police Chief Craig Stone said.

"This was done on purpose," Stone said.

Less than 2 minutes elapsed between the first call for help at 9:52 a.m. local time and the shots fired by campus police officer Alan Horujko, 28, Moll said.

The incident follows a stabbing attack in September at the Crossroads Mall in St. Cloud, Minnesota, where a man whose family came to the United States from Somalia wounded 10 people with a knife before he was shot to death by an off-duty police officer.

Authorities last month indicated the Minnesota attacker showed signs of radicalization and a Federal Bureau of Investigation special agent said his actions appeared to be "consistent with the philosophies of violent radical Islamic groups."

One person was critically injured in Monday's incident, Columbus fire officials said. Eleven people were treated at area hospitals, including 10 taken by ambulance.

Ohio State University Wexner Medical Center treated six victims, said Dr. Andrew Thomas, the chief medical officer. They included two with stab wounds and three others who had injuries from being hit with the vehicle.

Two other hospitals received five patients, who suffered from lacerations and injuries caused by the vehicle, Thomas said.

With nearly 60,000 students, the Columbus campus is the state's flagship public university.

CNN aired an image from a room at the university where students had barricaded a door with stacked chairs.

Columbus and university police continued their investigation with assistance from the FBI. The attack prompted university officials to warn students on Twitter to shelter in place.

The university campus remained open, although classes were canceled for the day.

President Barack Obama was briefed on the incident by Lisa Monaco, his homeland security adviser, said White House spokesman Josh Earnest.

Police said they are investigating whether it was a terrorist attack.</s>Attacker who wounded 11 at Ohio State University was a student

The man who drove a car into a crowd of students at Ohio State University on Monday and then attacked bystanders with a butcher knife, injuring at least 11, has been identified as a student at the university.

The suspect, Abdul Razak Ali Artan, who authorities said was about 20 years old, was shot and killed by a university police officer who arrived and brought down the attacker within a minute, officials said.

“This happened right before his eyes,” campus Police Chief Craig Stone said of Officer Alan Horujko, 28, who had been in the area on another call.

In a previous news conference, Stone said Artan had not “followed” the officer’s commands, and “the officer did what he had to do to end the threat.” Local officials have not suggested a motive for Artan’s actions, and Ohio Gov. John Kasich urged caution while the investigation unfolds.

“It’s our job to let the investigation take its due course, and at the end of the day we’ll find out what happened,” Kasich said. “We may never find out (why), but we’re going to have a lot more information. … Right now we have to have patience.”

After receiving a briefing on the attack, U.S. Rep. Adam B. Schiff, D-Calif., the top Democrat on the House Permanent Select Committee on Intelligence, said the incident “bears all of the hallmarks of a terror attack carried out by someone who may have been self-radicalized.” His office declined to release more information on how he reached that conclusion.

“The intelligence community is providing all necessary information and support to law enforcement as they investigate this individual’s motivations and background, and we hope to know much more very soon,” Schiff said in a statement.

An anonymous U.S. official told The Associated Press that Artan was born in Somalia and was a permanent U.S. resident. In an interview given to the Lantern campus newspaper in August, Artan said he was a Muslim and a new transfer student. Citing negative portrayals of Muslims in the media, he said he was confused and “scared” about where to pray on campus.

“I just transferred from Columbus State. We had prayer rooms, like actual rooms where we could go to pray because we Muslims have to pray five times a day,” Artan told the Lantern.

“I wanted to pray in the open, but I was kind of scared with everything going on in the media,” Artan said. “I’m a Muslim, it’s not what the media portrays me to be. If people look at me, a Muslim praying, I don’t know what they’re going to think, what’s going to happen.”

Artan said he decided to pray in a corner.

At least 11 people were treated for injuries at three hospitals, but none of the victims’ injuries was considered life-threatening, said Andrew Thomas, the chief medical officer for the Ohio State University Wexner Medical Center in Columbus.

The victims were primarily undergraduate and graduate students, and one was a faculty member, Thomas said. The injuries appeared to be evenly split between victims who had been hit by the car and those who had been injured by knife.

One victim came forward later because she had been “hiding in place,” Thomas said. She had been comforted by other students as they hid, university President Michael V. Drake said, and another victim had been driven to the hospital by another student, a stranger who had decided to help.

Footage published by the Lantern showed a young woman walking toward an ambulance with a pair of medical officials, holding what appeared to be an injured arm in the air.

The attack happened at 9:52 a.m., and less than five minutes later, university officials sent out a warning to students on campus: “Active Shooter on campus. Run Hide Fight.”

Police later said the attacker did not appear to have a gun and that he appeared to have acted alone.

“The guy ended up just coming and hopping the curb with his car and trying to mow down a couple people,” Jerry Kovacich, a third-year student in welding engineering, told the Lantern. “He lost control, and I think he ended up hitting three people, and then people were around the car. Somebody asked him if he was OK and the guy just hopped out of the car with a butcher knife and starting chasing people around.”

Horujko, who joined the campus Police Department in January 2015, was on the scene “in less than a minute and ended the situation in less than a minute,” Stone said.

“We believe injuries were minimized as a result of that,” said Monica Moll, the university’s public safety director.

The attack prompted a campus lockdown as police searched the area for possible other suspects, but the shelter-in-place order was lifted less than two hours later.

Officials said they were still waiting on a warrant to search a property associated with Artan. The FBI and the Bureau of Alcohol, Tobacco, Firearms and Explosives are assisting with the investigation.
Eleven people are hospitalized, one in critical condition, after a suspect rammed his car into a crowd, and then stabbed numerous people on Ohio State's Columbus campus. Police have declared the scene secure. The suspect, a refugee from Somalia, and a student at the university, is shot and killed by a police officer after he failed to obey orders to stop.
