Two suicide bombers have killed at least 22 people at a bazaar near the Afghan city of Kandahar, in an area used by drivers whose vehicles carry supplies for NATO.
About 50 people were also hurt in the attack, near the city's airport, which houses a large NATO airbase.
The BBC reports the first suicide attacker was on a motorcycle and struck a line of trucks waiting to supply NATO forces at Kandahar airport.
Minutes later, when a crowd had gathered a second attacker, on foot, detonated an explosives vest.
Officials say almost all of those killed in the latest attack were civilians, and included shopkeepers and passersby.
The Taliban have claimed responsibility for the attack.
