US troops killed 10 suspected Sunni militants and captured eight during an operation against al-Qaida fighters north of Samarra, the US military said Sunday. A US statement said the fight began when US soldiers came under fire Saturday as they approached the target area. Soldiers called for help from an unspecified aircraft, which killed eight people. Seven others were detained. One of those killed was believed involved in a March 6 jailbreak in which dozens of gunmen stormed the Badush prison north of Mosul and freed about 140 inmates, mostly insurgents, the US statement said.
