Safety fears remain in Bangladesh garment factories

Today marks three months since one of the world's worst industrial accidents.

More than 1,100 people were killed when a clothing factory collapsed on the outskirts of Bangladesh's capital Dhaka.

The disaster at Rana Plaza factory prompted a range of international retailers, human rights groups and trade unions to debate how to make textile factories in Bangladesh safer and protect workers' rights.

But, as Mahfuz Sadique reports from Dhaka, there is still much debate over what more can be done for the four million people employed in the country's all-important garment industry.
