At least six people have been killed in a series of terrorist bomb attacks in Shia-dominated areas in the Iraqi capital and the holy city of Karbala.
According to Iraqi officials, three civilians were killed after three roadside bombs went off simultaneously in the Husseiniyah area, northeast of Baghdad, on Sunday.
Eleven others, including three policemen, were also injured in the explosions.
An Iraqi soldier was killed when a bomb attached to his car exploded in the northern Utaifiya neighborhood of Baghdad.
And in the holy city of Karbala, at least two pilgrims were killed and 11 others injured after a bomber set off his explosives-laden belt.
The explosion took place in an area between the holy shrines of Imam Hussein (PBUH) and Imam Abbas (PBUH) in center of the city.
No group has yet claimed responsibility for the attacks. There has been a surge in the number of attacks against Shia Muslims in Iraq over the past months. Analysts believe the attacks aim at destabilizing the government of Nouri al-Maliki by sparking inter-communal violence.
On Thursday, a string of bomb attacks in and around the Iraqi capital killed at least 23 people and wounded more than 60 others.
