DHAKA, Bangladesh  -Police say two officers have been killed by attackers who stormed a restaurant popular with foreigners in a diplomatic zone in the Bangladeshi capital, Dhaka, taking dozens of hostages and exchanging gunfire with security forces.

Hospital authorities said another 25 officers and one civilian were being treated for injuries, including 10 people listed in critical condition. The injuries include bullet wounds and broken bones, they said.

The Islamic State's Amaq News Agency said the attack on the restaurant was carried out by "Islamic State commandos," according to the SITE Intelligence Group which monitors jihadist activity. Bangladesh authorities did not immediately respond to the claim.

As many as nine gunmen attacked the Holey Artisan Bakery in Dhaka's Gulshan area on Friday night.
