Kandahar - At least 23 people were killed and 50 other civilians injured in three bomb attacks in southern Afghanistan on Wednesday, officials said.
"An explosive-packed motorbike blew up on the road to Kandahar airport and subsequently a suicide bomber detonated himself among the people gathered at the scene," Kandahar police chief Abdul Raziq said.
The attacks occurred in a bazaar in the eastern part of Kandahar's military airbase, another police official said. Kandahar is one of the largest Nato bases in southern Afghanistan.
Kandahar Deputy Police Chief Rahmatullah Atrafi said two suicide bombers blew themselves up amid the crowds that had gathered after first bomb went off outside the airport.
He said eight security guards and 15 civilians were killed.
"As [the] first bomb went off first at the bazaar outside the airport and people gathered, two suicide bombers walked into the crowd and detonated their explosives," Atrafi said.
He said the guards worked for the Supreme security company, a US firm that provides logistics support to the Nato-led International Security Assistance Force.
Qari Yousuf Ahmadi, a Taliban spokesman in southern Afghanistan, claimed responsibility for the attacks, saying they had killed 17 foreign soldiers in the attacks carried out by their fighters.
Kandahar airport is located near the Nato base. Kandahar is known as the birthplace of the Taliban movement that has been waging an insurgency for more than a decade.
