Bangladesh has begun two days of mourning for 20 people, mostly foreigners, who were killed when militants attacked a popular restaurant in the capital Dhaka.
During the attack, which has been claimed by the so-called Islamic State militant group, seven gunmen took a number of hostages, and reportedly tortured and killed those who could not recite verses from the Qu'ran.
Thirteen hostages were saved after police launched a rescue operation.
Bangladesh will stand up and fight the "terror threat" that has mushroomed in its backyard, the country's prime minister has said.

Most of the 20 people killed by the attackers were foreigners, among them a US citizen.
At least 13 people have been rescued following the raid, according to a Bangladeshi official.
