At least three people have been killed in a suicide attack in Afghanistan, the day after US Secretary of State John Kerry arrived there for crucial talks.
A car blew up outside a police station in Jalalabad. Two Afghan policemen and a civilian died. Several people were injured.
Most foreign forces are due to withdraw from the war-shattered country by the end of next year but Washington wants to maintain a military presence.
Kerry and Afghan President Hamid Karzai have narrowed some of their differences in discussing a security deal.
One obstacle has been the US refusal to guarantee protection for Afghanistan if attacked, amid fears this could lead to calls for offensive action against another ally, neighbouring Pakistan.
