Two soldiers with the US-led coalition were killed in southern Afghanistan when their vehicle struck a mine planted on a busy road, the force announced.
The soldiers were hit while on a security patrol with Afghan forces on Friday, it said in a statement.
The attack was similar to scores carried out by Taliban militants active in the area but there was no immediate claim of responsibility.
“Two coalition force soldiers were killed March 21 when their vehicle struck an improvised explosive device in Kandahar province,” the statement said.
The coalition did not give the nationalities of the troops.
The force includes about 18,500 US soldiers and about 1,500 of other nationalities.
More than 30 international soldiers – in the coalition and a separate NATO-led force – have been killed in Afghanistan this year, most of them in hostile incidents related to the Taliban insurgency.
