At least 30 people have been killed in Dhaka

At least 30 people have been killed and hundreds are feared trapped after an eight-storey building collapsed in the Bangladeshi capital, Dhaka, emergency services say.

Frantic efforts are under way to rescue those beneath the debris. At least 200 were injured by the collapse.
The army is helping with the rescue operation on the outskirts of Dhaka.
Building collapses are common in Bangladesh where many multi-storey blocks are built in violation of rules.
The eight-storey building contained a clothing factory, a bank and several other shops. It collapsed during the morning rush hour.
Many people have gathered near the scene looking for friends and relatives.
The BBC's Anbarasan Ethirajan, in Dhaka, says that it is not yet clear what caused the collapse but local media reports said a crack was detected in the block on Tuesday.
