Iraqi police arrest gunmen - UPI.com BAGHDAD, May 27 (UPI) -- Iraqi security forces in Baghdad have arrested four gunmen suspected in sectarian-motivated killings, officials said. Al-Shorfa newspaper Saturday quoted the director of Northern Baghdad police operations, Lt. Col. Nasif Radhi al-Kanani, as confirming the arrests, saying "Our unit force arrested four Shiite gunmen involved in sectarian-motivated killing." Kanani said an arrest warrant issued in 2006 accused the four of running death squads, which prompted the suspects to flee to neighboring Iran. The Socialist Forum said Sunday officials suspected they had re-entered Iraq in 2011 to resume their activities under Iranian sponsorship. Al-Shorfa said security forces found weapons and money where the accused had been hiding, indicating they were planning further attacks against Sunni citizens.
