At least 33 people were killed on Wednesday, most of them in a Baghdad car bomb attack, a day after multiple bombings in Iraq left 64 dead and revived fears of civil war. Bombers struck again in Baghdad's southeastern neighbourhood of Jadid at about midday, killing 23 and wounding 58 by blowing up a car on the main road which also housed a market.At least four police officers were killed when gunmen attacked a police convoy in northern Iraq on Wednesday, a police source said. The attack occurred as about 50 officers were being driven in minibuses to Tikrit, north of Baghdad, after a training course in the Kurdish city of Sulaimaniya. At least seven were wounded and many others feared seized, the source said. Three Iraqi policemen said that they had survived the ambush and told the source that around 10 of their colleagues had been abducted. The fate of the other policemen was unclear. Six others were killed in separate bombings and shootings across Iraq on Wednesday. At least 85 were wounded in all these attacks.
