US-led foreign convoy hit by blast near Kandahar airpor
The attack was carried out on Friday as the convoy was moving toward the airport.
Over a dozen people were also wounded in the blast. However, there has been no confirmed report on the number of casualties.
The Taliban militants have claimed responsibility for the attack.
In another incident in the western province of Farah, the Taliban militants attacked a convoy of fuel tankers belonging to US-led forces on Thursday.
According to Afghan officials in Farah, four tankers have been destroyed in the assault, but Taliban claim to have targeted ten tankers and killed eight guards of the convoy.
Provincial officials have rejected the Taliban claim, saying that four members of the group were killed in the incident.
Hundreds of NATO logistic convoys and oil containers have been attacked in different parts of Afghanistan in recent years.
The Taliban attacks have been rampant since the militant group launched its annual offensive in April against Afghan government forces and US-led troops stationed in the country.
The US-led war in Afghanistan removed the Taliban from power in 2001, but insecurity remains in the country, despite the presence of thousands of US-led troops
