Police are blocking all access to streets near the Holey Artisan Bakery in Dhaka's Gulshan area as security officials look for evidence after the weekend hostage crisis that left 28 dead, including six attackers and 20 of the hostages.

Sunday is the first of two days of national mourning for the victims. In the morning, investigators from Bangladesh and Japan visited the restaurant to collect evidence. The dead included nine Italians and seven Japanese development workers.

After the hostage siege began Friday night, authorities said 25 officers and one civilian had been wounded, and 10 of them were in critical condition. People were not allowed near the hospital on Saturday and Sunday, and hospital staff would give no updates on those injured.

Some of the 13 rescued hostages also were treated for injuries.
