BBC News Dhaka building collapse Fears f
Hundreds of people are still missing after Wednesday's collapse of a building in Bangladesh which killed over 300 people, local officials say.
More than 40 people have been rescued since Thursday from the Rana Plaza building near Dhaka, which housed clothes factories.
Prime Minister Sheikh Hasina has called for special prayers to be held across the country later for the victims.
Angry protesters have taken to the streets of Dhaka for a second day.
They are demanding the authorities arrest the owner of the collapsed building and improve conditions for garment workers.
Police said that at least 10,000 people had gathered for the demonstrations and described the situation as "volatile".
Police used tear-gas and rubber bullets to break up the crowds, which had blocked roads, torched buses and attacked textile factories.
