Reported 20 hostages have been killed in Dhaka Bangladesh which has been claimed by Islamist extremist. All the attackers in the deadly assault on a cafe in Dhaka were Bangladeshi citizens, and five of them were militants that police had tried to arrest previously, Police Inspector General Shahidul Hoque told reporters on Saturday.

Authorities also released the nationalities of the hostages who were found dead inside the Holey Artisan Bakery cafe after Bangladeshi troops stormed the cafe early Saturday morning, ending a nearly 11-hour siege.

Nine of the victims were Italian, seven were Japanese, one was from India, two were Bangladeshi and one was a U.S. citizen of Bangladeshi origin, according to the country’s Joint Force Command. Eleven of the victims were male and nine were female.

Also two police officers had been killed in a gunfire exchange earlier in the standoff, authorities said. The attack in the affluent, diplomatic enclave was the deadliest and boldest act of terror in a country that has become increasingly numb to ever-escalating violence by Islamist militants.

The victims were among roughly three dozen people taken hostage when attackers stormed the cafe Friday evening with guns, explosives and sharp weapons, authorities said. Some guests and workers managed to escape, jumping from the bakery’s roof. Others crouched under chairs and tables as the gunmen fired indiscriminately, witnesses said.

Early Saturday morning, military commandos moved in. By the end, 13 people had been rescued and 20 were dead, officials said. Six terrorists were killed and one was captured alive, Bangladeshi Prime Minister Sheikh Hasina said Saturday.
