Police say the death toll from the collapse of a garment factory building in Bangladesh has soared past 1,100 as recovery operations continue.

Doctors say a seamstress who was rescued 17 days after the eight-storey building collapsed is recovering in a hospital, but is exhausted, panicked and dehydrated.

“We will not leave the operation until the last dead body and living person is found,” said Maj. Gen. Chowdhury Hasan Suhrawardy, the head of the local military units in charge of rescue operations.
