A car bomb has killed at least 11 people at a market in south-eastern Baghdad, a day after more than 80 people were killed in a series of suicide attacks in Baghdad and in a north-eastern town.

Police say the blast in the Diyala Bridge section of the capital has also wounded 15 people.

They say the toll could increase.

The attack comes as more than 50 Iraqi politicians from across the country's sectarian divide are scheduled to hold reconciliation talks in Cairo, Egypt, aimed at easing the bloodshed that has plagued Iraq since the US-led invasion in 2003.

On Friday, 77 people were killed and more than 80 wounded in twin suicide bomb attacks on mosques in the town of Khanaqin.

A suicide car bomb also detonated outside a popular hotel in Baghdad, destroying an apartment building and killing six people.

More than 40 were also wounded.
