The renewed violence came as Afghan President Hamid Karzai acknowledged at a news conference that regular payments his government has received from the CIA for more than a decade would continue. Karzai also said that talks on a U.S.-Afghan bilateral security agreement to govern future American military presence in the country had been delayed because of conditions the Afghans were placing on the deal.

The U.S.-led coalition reported that five international troops were killed by a roadside bomb in southern Afghanistan, and coalition spokesman Capt. Luca Carniel confirmed that all five were American.
