Six killed in bike bomb attack on mosque
In Baghdad, guerrillas fired rockets at dawn into a hotel used by Westerners and hundreds of US troops stormed houses and shops in Tikrit overnight in the hope of capturing those behind a wave of such attacks.
In Baquba, 40 miles north of Baghdad, unknown attackers strapped a gas cylinder packed with explosives to a bicycle and left it outside a small Shi'ite mosque close to people praying on the pavement because of lack of space inside.
