The death toll caused by two car bombings in Baghdad's Sadr city on Saturday night rose to 13 in addition to 52 injured, a police source said.

The blasts happened in quick succession in the capital's major Shiite neighborhood late in the night, the source told Xinhua on condition of anonymity. Earlier he put the toll at 10 dead and 32 injured.

The death toll could further rise as some injured were in serious conditions, he added.

Several were killed and dozens more wounded in other separate bombings and shootings in the evening in and near Baghdad.

The string of attacks cast a pall over the major Muslim holiday, the Eid al-Adha. Early in the day time, multiple attacks claimed a score of lives across the violence-laden country. Religious festivals and annual holidays are usually marked by a spike of violence in Iraq.
