A new wave of deadly bombings in Iraq has dashed hopes the country might be getting to grips with insurgents. In Baghdad this morning a suicide bomber struck at a crowded market where US troops were patrolling. Police say 12 people were killed, including three of the soldiers.In the northern city of Kirkuk, another bomber triggered an explosives vest as local anti-al Qaeda militia queued to collect their wages. Eight members of the paramilitary group were killed. Another bomb, this one placed in a bin at a Baghdad police station, claimed three more lives. These attacks come a day after a car bomb in the capital claimed 40 civilian lives and left more than 80 people injured. Perceived improvements in security had convinced the US and its allies they could withdraw from the country by the end of 2011. However, as the bombings continue, so do questions over how well Iraq’s security personnel will cope on its own.
