A suicide attacker exploded himself on a highway in Qalat city of southern Afghanistan's Zabul province Thursday, injuring a civilian shopkeeper, a local official said.
It occurred at around 12 o'clock (GMT 0730) on a highway linking though Kabul from the north to the southern Kandahar province when the bomber apparently wanting to target some Afghan army vehicle exploded himself prematurely, a spokesman for Zabul governor told Xinhua via phone.
No army vehicle passed by when the man detonated the bomb, the official said.
No group has taken the responsibility for the attack.
War-torn Afghanistan has seen a resurgence of Taliban-related militancy since around 2004 and rising violence claimed over 6,000lives in 2007.
