Photographer Who Provided Eyewitness Account of Kabul Attack Escapes

Massoud Hossaini, the 34-year-old Pulitzer Prize-winning photographer with The Associated Press who helped tell the world about the attack on The American University of Afghanistan in Kabul through Twitter, has escaped, according to the AP.

"Help we are stuck inside AUAF and shooting flollowed [sic] by Explo this maybe my last tweets," he tweeted just as news of the attack broke.

The tweet, which was shared hundreds of times before Hossani removed it, painted a dire portrait to outsiders of the attack that was going on inside of the school.

The gunfire that was reported in the vicinity of the school has now stopped, according to a source in the Kabul Police Force. The same source told ABC News that two people were killed and five were injured in the attack.

The victims have not been publicly identified.

Hossaini was in a classroom with 15 students when he heard an explosion on the southern flank of the campus, according to the AP.

"I went to the window to see what was going on, and I saw a person in normal clothes outside. He shot at me and shattered the glass," Hossaini told the AP, adding that he fell on the glass and cut his hands.

The students then barricaded themselves into the classroom, pushing chairs and desks against the door, and staying on the floor, according to the AP. Hossaini and about nine students managed to escape from the campus through a northern emergency gate, he told the news agency.

"As we were running I saw someone lying on the ground face down, they looked like they had been shot in the back," he said.

Hossaini won a Pulitzer Prize in 2012 while working with Agence France-Presse, "For his heartbreaking image of a girl crying in fear after a suicide bomber's attack at a crowded shrine in Kabul," according to the Pulitzer's website.
