Charlotta Turner, professor in Analytical Chemistry, received a text message from her student Firas Jumaah in 2014 telling her to to assume he would not finish his thesis if he had not returned within a week. 
 
 He and his family were, he told her, hiding out in a disused bleach factory, with the sounds of gunshots from Isis warriors roaming the town reverberating around them. Jumaah, who is from Iraq, is a member of the ethno-religious group Yazidi hated by Isis. 
 
 "I had no hope then at all," Jumaah told Lund's University Magazine LUM . "I was desperate. I just wanted to tell my supervisor what was happening. I had no idea that a professor would be able to do anything for us." 
 
 Jumaah had voluntarily entered the war zone after his wife had rung him to say that Isis fighters had taken over the next-door village, killing all the men and taking the women into slavery. 
 
 "My wife was totally panicking. Everyone was shocked at how IS were behaving," he said. "I took the first plane there to be with them. What sort of life would I have if anything had happened to them there?" 
 
 But Turner was not willing to leave her student to die without trying to do something. 
 
 "What was happening was completely unacceptable," she told LUM. "I got so angry that IS was pushing itself into our world, exposing my doctoral student and his family to this, and disrupting the research." 
 
 She contacted the university's then security chief Per Gustafson. 
 
 "It was almost as if he'd been waiting for this kind of mission," Turner said. "Per Gustafson said that we had a transport and security deal which stretched over the whole world." 
 
 Over a few days of intense activity, Gustafson hired a security company which then arranged the rescue operation. A few days later two Landcruisers carrying four heavily-armed mercenaries roared into the area where Jumaah was hiding, and sped him away to Erbil Airport together with his wife and two small children. "I have never felt so privileged, so VIP," Jumaah told LUM. "But at the same time I felt like a coward as I left my mother and sisters behind me."

 Luckily the rest of his family survived Isis occupation, while Jumaah back in Sweden completed his PhD and now works for a pharmaceuticals company in Malmö. The family has almost finished paying the university back for the rescue operation. 
 
 "It was a unique event. As far as I know no other university has ever been involved in anything like it," Gustafson said. ||||| Breaking News Emails Get breaking news alerts and special reports. The news and stories that matter, delivered weekday mornings.

 On an August day four years ago, Swedish chemistry professor Charlotta Turner received a surprising text message that would change the life of one of her graduate students. 
 
 Firas Jumaah had returned to his native Iraq days earlier, fearing for the safety of his wife and two children who had traveled there for a family wedding. He had initially stayed behind to complete his lab work at Lund University in southern Sweden. 
 
 While with his family in Iraq, Jumaah sent his supervisor a text message asking her to remove him from the doctoral program if he wasn’t back in Sweden within a week.

 Surprised by the message, Turner, 48, called Jumaah. It was then that she found out that his family was facing a life-and-death situation. 
 
 “He was very sad and crying,” Turner told NBC News. “I could hear that the situation was hopeless and they had to flee.” 
 
 Jumaah's family had returned to visit their home country of Iraq before violence began. But while he was there the so-called Islamic State conducted a deadly offensive in northern Iraq. 
 
 On Aug. 3, ISIS attacked the city of Sinjar near to where Jumaah’s family was, massacring and enslaving thousands of Yazidis — a religious minority to which Jumaah and his family belong. 
 
 “He realized one day that things were getting really serious there,” Turner said. “He was very worried and he just left.” 
 
 Jumaah’s plan was to go in and bring his family back to Sweden, but when he arrived, most borders were closed because of a mass exodus of refugees. He also couldn’t go back to the airport. So they waited. 
 
 But the situation only grew worse because ISIS kept advancing — and, at one point, came within 12 miles of their house. 
 
 Over the phone, Jumaah told Turner that he and his family were preparing to go into hiding in Iraq’s northern mountains. She told him not to give up and started looking for ways to rescue the family. 
 
 “It was very spontaneous,” she said. “For me, it was obvious that I should help and bring them home.” 
 
 She approached the university’s security chief at the time, who found a company that could go in with armed men and rescue Jumaah and his family.
– Four years ago, a chemistry professor got a text from her grad student: If I'm not back in a week, cut me from the doctoral program. Charlotta Turner called him right away: "He was very sad and crying,” the 48-year-old prof at Lund University in Sweden tells NBC News. "I could hear that the situation was hopeless and they had to flee." The student, Firas Jumaah, was visiting his native Iraq to help family members during a brutal 2014 ISIS attack targeting Yazidis—a religious minority that includes his family. The terror group had just enslaved and massacred Yazidis by the thousand in nearby Sinjar. Now Jumaah and family were planning to flee to the mountains. "I had no hope at all," says Jumaah, per the Local. "I was desperate." But Turner took action. She spoke to Lund University's then-security chief, who contacted a company that sent mercenaries into northern Iraq. Only days later, four armed mercs on two Landcruisers blazed into the place where Jumaah was hiding, and rushed him to Erbil Airport with his wife and two young kids. "I have never felt so privileged, so VIP," he says. "But at the same time I felt like a coward as I left my mother and sisters behind me." Seeing his colleagues back in Sweden, he was speechless: "I just cried," he says. Yet Jumaah finished his PhD and found work at a Malmo pharmaceuticals company, and his family survived. The bill: roughly 60,000 kroner ($6,613), which his family has nearly finished paying. “If they told me to pay 200,000 kronor, I would,” says Jumaah. (The UN is finding fresh ISIS horrors.)
