IS affiliates claim Dhaka cafe attack

A news agency run by Islamic State says the militant group's affiliates are responsible for an attack on a cafe in Bangladesh, where gunmen are holding hostages as police laid siege to the building.

A tweet from the Amaq news agency also said more than 20 people had been killed in the attack in Dhaka on Friday night.

Bangladeshi police however reported only that two police had been shot dead and said they were trying to free the hostages peacefully.
