A bomb planted inside a minibus exploded in Baghdad's Shia Sadr City area today, killing at least two people and wounding six, police sources said.
No further details were immediately available.
Sunni insurgents have stepped up bombings of buses in recent weeks, stirring already high sectarian passions. A bomb inside a minibus in Sadr City earlier this week killed two people and wounded five.
Sadr City, a sprawling slum in eastern Baghdad, is a stronghold of radical Shia cleric and militia leader Moqtada al-Sadr, a growing political figure in the ruling Shia coalition.
