Two NATO soldiers were killed in an attack in Afghanistan Sunday, ISAF said, while police said at least two children were also killed as a suicide bomber targeted a NATO convoy.
"Two International Security Assistance Force service members died following an insurgent attack in southern Afghanistan today," NATO's ISAF said in a statement, without giving further details.
Two children were also killed and several civilians were wounded in the suicide attack in Tirin Kot, capital of Uruzgan province, the provincial police chief told AFP.
"In a suicide attack against an ISAF convoy in Tirin Kot this morning two children were killed and several other civilians were wounded. There have been some casualties to ISAF troops too," said General Matiullah Khan.
The attack came as NATO leaders gathered in Chicago for a summit which will be dominated by plans to pull some 130,000 alliance troops out of Afghanistan by the end of 2014.
It follows a rocket attack by Taliban insurgents on a NATO base in the eastern Afghan province of Kunar on Friday that killed two international soldiers and wounded six.
At least 162 ISAF troops have died in Afghanistan this year, according to an AFP count based on the the website icasualties.org. More than 3,000 have been killed since the US led an invasion to topple the Taliban in late 2001.
