Kabul, Afghanistan (CNN) -- A suicide bomber in a car blew himself up in front of an airport in southern Afghanistan on Thursday, killing at least seven civilians, police said.
The fatalities in the blast at the Kandahar International Airport included two children, with at least eight people injured, the local governor's office said.
A Taliban spokesman said the militant group is responsible for the attack and was targeting a convoy of foreigners nearby.
Casualties included foreigners, according to Qari Yousuf Ahmadi, the spokesman.
NATO's International Security Assistance Force said the attack hit an entry check point, but foreign troops are not among the casualties.
The attack is the latest in Afghanistan this week, including a suicide bombing that killed 13 people in Helmand province Wednesday.
The attack occurred after a motorcyclist sped up to a group of people, wounding 22 others in addition to the fatalities, the Helmand governor said.
