Boston suspects planned to bomb New York, says mayor The two Boston bombing suspects planned to travel to New York and use their remaining explosives in Times Square, the city's mayor Michael Bloomberg said on Thursday. According to Mr Bloomberg, Dzhokhar Tsarnaev, the 19-year-old surviving suspect, told investigators about the intention to travel to New York during interrogations this week. "Last night we were informed by the FBI that the surviving attacker revealed that New York City was next on their list of targets," said Mr Bloomberg. He and his older brother intended to drive to New York and detonate those explosives in Times Square. Ray Kelly, New York police commissioner, said that the two brothers decided "spontaneously" that they would drive to Times Square after hijacking a car last Thursday evening in Boston when the FBI started to circulate their photos. Investigators said that they found explosives in the car, including a bomb made from a pressure cooker similar to those which exploded at the finishing line of the marathon last week. Tamerlan Tsarnaev, the older of the two brothers suspected of exploding the bombs, died after a shoot-out with police on Friday. Mr Bloomberg's statement came as the father of the two Boston bombing suspects said on Thursday that he would travel to the US to bury his dead son and as political recriminations over the terrorist attack gathered steam in Washington. Anzor Tsarnaev, who lives in the Russian city of Makhachkala in Dagestan, denied that his sons had planted the bombs at the marathon finishing line, killing three people last Monday. "I am going there to see my son and bury my older one," he said. I have no bad thoughts, I'm not planning any bombings, I don't want to do anything, I'm not offended by anyone. I want to know the truth, what happened. I want to work it out. He said he was likely to travel in the next few days, although he did not have a plane ticket. Republican politicians have stepped up pressure on the Obama administration over what some see as the mishandling of intelligence information by the authorities about Tamerlan Tsarnaev. Two Republican senators, John McCain of Arizona and Kelly Ayotte of New Hampshire, have called for hearings into "the failure to prevent this tragedy." "In a string of apparent intelligence-sharing lapses, Tamerlan Tsarnaev was able to slip through the cracks and carry out this devastating attack," the senators said. Republican members of Congress are asking questions about probes into Mr Tsarnaev after the Russian authorities contacted both the Federal Bureau of Investigation and the Central Intelligence Agency with suspicions about his links to radical groups. They are also asking questions about reports that the CIA wanted Mr Tsarnaev's name to be put on a terror watch list because of the Russian suspicions about his activities. Mr Tsarnaev was investigated in 2011 by the FBI, which found no evidence that he was involved in terrorist activities. According to government officials, his name "pinged" - came up on the monitoring system kept by law enforcement agencies - when he travelled to Russia in 2012. However, by the time he returned six months later, the FBI alert had expired and his name did not come up. "Between Benghazi and Boston, we're going backward in national security," said Republican senator Lindsey Graham on Wednesday. This administration is letting its guard down and it's beginning to show. Adam Schiff, the ranking Democrat on a House intelligence subcommittee, said on Thursday he does not believe the FBI and CIA failed to share relevant information with each other regarding Mr Tsarnaev. "This information was put in a database, it was shared among different agencies, it was shared with a joint terrorism task force, and that's exactly what should happen," he said. Some are racing to say that the FBI dropped the ball or the agencies weren't talking to each other, and that just doesn't seem to be the case. Mr Bloomberg said that the investigation in Boston had shown the importance of surveillance cameras, which have become prevalent in New York since the 2001 attacks but which have attracted criticism on civil liberties grounds. He also said that it was important for New York's police to expand its own counter-terrorism capabilities. Russian President Vladimir Putin said on Thursday that the Boston bombings should encourage stronger security co-operation between Moscow and Washington. "This tragedy should push us closer in fending off common threats, including terrorism, which is one of the biggest and most dangerous of them," Mr Putin said, according to the Associated Press.
