Loud explosions shook the Iraqi capital Monday. Early in the morning, a roadside bomb exploded in Suq Hamada Street, near the insurgent stronghold of Haifa Street, which has been the scene of heavy fighting in recent days, Interior Ministry official Col. Adnan Abdul-Rahman said. No one was hurt in the blast. Around noon, a second blast rocked the city, which has seen almost daily attacks as insurgents battle to undermine the interim government of Prime Minister Ayad Allawi and force the United States and its allies out of Iraq.
