A suicide car bomb struck a U.S. military patrol on a busy street in Iraq's northern city of Mosul on Sunday, wounding at least 34 bystanders, police said. Police did not know of any deaths, nor whether any U.S. soldiers in the convoy were also casualties of the blast, which destroyed several cars and local shops. Violence across Iraq has risen in the past two months after nearly a year of decline, as militants seek to regain lost ground. Mosul is plagued by a stubborn insurgency, despite repeated efforts to stamp it out.
