Three students of American universities were among those killed by gunmen in Dhaka, Bangladesh, during an 10-hour hostage situation at a bakery.

{mosads}Two of those killed were attending Emory University, the school announced in a Facebook post Saturday morning. Abinta Kabir was a sophomore from Miami, and Faraaz Hossain, from Dhaka, was a graduate student at Emory’s business school.

“The Emory community mourns this tragic and senseless loss of two members of our university family,” the school said. “Our thoughts and prayers go out on behalf of Faraaz and Abinta and their families and friends for strength and peace at this unspeakably sad time.”

Also among the murdered hostages was 19-year-old Indian citizen Tarushi Jain, a student at University of California at Berkeley, according to CNN.

Twenty of the hostages were killed, as were two officers and six of the seven attackers, according to CNN. The seventh was captured alive. 

Bangladeshi military officials told CNN the attackers used guns, explosive devices and “a lot of sharp domestic weapons,” and that all hostages killed were foreigners.

The Islamic State in Iraq and Syria have claimed credit for the attack, but U.S. officials were not certain.

The attack on Holey Artisan Bakery in Dhaka, the nation’s capital, took place during the Islamic holy month of Ramadan.

The gunmen held the hostages during a 10-hour standoff.
