The Islamic prayer service was held a day after the army ended the nearly three week, painstaking search for bodies among the rubble and turned control of the site over to the civilian government for cleanup.
A statement from Prime Minister Sheikh Hasina, mourning the deaths and thanking the rescuers, was read out ahead of the prayers.
Government ministers and senior leaders joined the prayer, even as officials said at least 176 people are still missing after 20 days of search operations as army troops, fire fighters and ordinary volunteers rescued 2444 people alive.
Major General Chowdhury Hasan Suhrawardy, the military commander who had been supervising the site, thanked all those involved in the rescue work.
