Dhaka

Bangladesh police have said security forces may have mistakenly shot dead a hostage during the Dhaka restaurant attack, believing he was an attacker.

Saiful Islam, a senior police official in Dhaka, said Saiful Islam Chowkidar, a pizza maker at the Holey Artisan restaurant, was among six men who were killed when officers stormed the eatery to end a 12-hour siege.

Twenty people, mostly foreigners, were killed when militants attacked the popular restaurant in the capital city on Friday night.

During the attack, which has been claimed by the so-called Islamic State militant group, several 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.

• Police had tried to arrest five of cafe gunmen before attack

Bangladesh's home minister has denied that so-called Islamic State had any role in the deadly cafe attack.

Asaduzzaman Khan also dismissed the involvement of al Qaeda, saying that the gunmen were home-grown militants.

Mr Khan added that the gunmen in the attack at the Holey Artisan Bakery had made no demands when police had asked their intentions.

Three of the six gunmen killed were under the age of 22, he said, and added that they had been missing for six months.
