A rocket is launched from an unknown location in this image taken from a video grab obtained by Reuters Television on October 14, 2007. Two Shi'ite militant groups have claimed responsibility for deadly bomb attacks on Polish targets in Iraq, saying they were in response to the alleged torture of Iraqi detainees by troops from Poland.
