WASHINGTON (AFP) - The US military said Thursday three more soldiers died in Afghanistan in recent days, raising the death toll for August to 69 troops - in the worst month yet for American forces in the war. Two US Army sergeants were killed in the southern Helmand province on August 25 when their vehicle struck a homemade bomb planted by insurgents, the Pentagon said in a statement. Another soldier, Private First Class Alberto Obod, 26, of Orlando, Florida, died August 28 in Kandahar province from injuries suffered after his vehicle rolled over, it said.
