As many as six people were killed and 50 more were wounded in a heavy mortar and rocket attack on a camp housing the Iranian dissident group Mujahedeen al-Khalq. Three Iraqi policemen were also wounded. As many as 40 mortars or rockets rained on the camp during the assault. One camp spokesperson claimed that 100 people were wounded. No one has, as yet, taken responsibility for the attack, but the Badr Brigade maintains a presence in the area where the rockets were launched.

The controversial dissidents, listed as terrorists by some, had been living for decades at Camp Ashraf in eastern Iraq until last year when Baghdad forcibly moved them to Camp Liberty where today’s attack took place.

Meanwhile, at least one Iraqi was killed and five others were wounded in separate violence.
