'More than 50 people have died in two separate car bomb attacks in Iraq. At least 34 of them were killed when a bomb exploded at a crowded market in Sadr City - a mainly Shia area in the Iraqi capital.
A few hours later at least 20 people died in a blast near a courthouse in the northern city of Kirkuk.There has been an upsurge in sectarian violence in Iraq in recent months. Two weeks ago, a car bombing in Sadr City killed 66 people.'
