A car bomb blew up this evening outside a Shia mosque in Baghdad's northeastern al-Hurriya neighborhood, killing 25 people and injuring 43.
It brought the death toll in bombings and shootings today to more than 60, with as many as 150 people injured.
The attacks are believed to have been co-ordinated and follow the lifting yesterday of a curfew imposed to prevent further sectarian violence between Shia and Sunni Muslims.
Three earlier blasts, which occurred within minutes of each other, were caused by two car bombs and one suicide bomber in central and eastern areas of the Iraqi capital.
One car bomb near a market in the central Karada district left six dead and 16 wounded.
While 23 people died and 51 were wounded when a suicide bomber blew himself up in the al-Amin neighbourhood.
And in the Jadida area in the east of the city, four civilians were killed and 11 injured in another car bomb attack.
Two British soldiers have been killed in an attack on a patrol in Amara in southern Iraq.
A third soldier was wounded in the incident, but his injuries are not thought to be life threatening.
Earlier, a bomb badly damaged the tomb of Saddam Hussein's father in his home town of Tikrit.
