Bangladesh factory collapse: 149 people still missing

The number of people known to have died in last week's factory collapse in Bangladesh has passed 400, and a further 149 are still listed as missing.

On Wednesday thousands of people took part in a protest march through Dhaka, demanding better working conditions.

Meanwhile, Pope Francis denounced those conditions as "slave labour", saying he was shocked by reports that some of the labourers were paid just 38 euros ($50) a month.
