KABUL - Afghanistan's president Hamid Karzai said US forces had bombed a home in Helmand killing a small child and wounding two women on Thursday and condemned the attack as another sign of disregard for civilian life, his spokesman said.The strike could not have come at a worse time, as Karzai is engaged in a stand-off with the American government over a bilateral security agreement that will help shape the presence of US troops in Afghanistan after 2014."It shows that US forces have no respect for the decisions of the Loya Jirga [council of elders] and life of civilians in Afghanistan," said Karzai's spokesman, Aimal Faizi.
