BAGHDAD, May 18, SPA -- About 50 suspected insurgents attacked a coalition base in the center of a northern Iraqi city Friday, sparking a battle with U.S. soldiers and helicopters that killed at least six militants, the Iraqi army said. The fighting took place in Baqouba that has seen a recent spike in violence largely blamed on militants who fled a 3-month-old security crackdown in Baghdad, the Associated Press reported.--SPA www.spa.gov.sa/450804
