Four rockets fired from eastern Baghdad on Thursday landed around the Iraqi capital's Green Zone, home to government buildings and foreign missions, police said, as political unrest intensified.
There were no immediate reports of casualties from the strikes and no claim of responsibility, two police officers said. A number of Shi'ite Muslim militant groups have offices and supporters in eastern Baghdad.
A similar attack on Wednesday wounded seven members of the Iraqi security forces in the Green Zone, and appeared to add a new dimension to a contest among power-hungry politicians.
