Three students at universities in the United States, including a US citizen and an Indian citizen, were among those killed in a militant attack in Bangladesh, university officials, the Indian government and a source said on Saturday.
The State Department confirmed one US citizen was killed, but gave no details.
"We can confirm that a U.S. citizen was also among those senselessly murdered in this attack," it said in a statement. The White House condemned the attack in the country's capital Dhaka, which it said resulted in as many as 20 deaths, including that of the American.
"We remain in contact with Bangladeshi authorities and have offered any assistance necessary," it said.
Islamic State claims to be responsible for one of the most brazen attacks in the South Asian nation's history, killing more than a dozen foreigners in an attack on a restaurant before security forces stormed the building and ended a 12-hour standoff on Saturday.
