A suicide attack targeting a NATO convoy in the southern Afghan city of Kandahar has killed seven civilians, officials said.

The attacker detonated his explosives near the Kandahar International Airport, the province's Media and Information Centre (KMIC) said. 

Two children were among the dead, KMIC said. Eight people were wounded, including one woman and two children.

The Taliban claimed responsibility for the attack, AFP news agency reported. Spokesman Qari Yousuf Ahmadi said the target was "the bullet-proof vehicles of foreign forces".

The attack comes a day after a motorcycle bomber killed at least 13 people in a market in neighbouring Helmand province.

Southern Afghanistan, the hub of Taliban operations, has seen most of the violence in the decade long war against the US-led NATO coalition.

Thousands of families have been forced to flee the violence and relocate to refugee camps in Kabul, the capital, and other areas.
