NATO say one of its service members was killed Sunday in a bomb blast in southern Afghanistan.
On Saturday, NATO said two service members died in two bomb attacks in the southern and northern parts of the country.
NATO did not release the identity or nationality of those killed in either the Sunday or Saturday attacks. However, the Swedish military identified the soldier killed in the north Saturday as one of its own. It said two other troops were wounded when their vehicle was hit by a roadside bomb.
Also Saturday, NATO says five insurgents were killed in an airstrike in the country's east. Elsewhere, Afghan and coalition forces detained several suspected insurgents during three overnight operations aimed at capturing leaders from the Taliban and Haqqani network.
NATO has been supporting efforts by Afghan President Hamid Karzai to reconcile with Taliban militants.
A spokesman for Afghanistan's High Council for Peace, Bryali Helali, told VOA Saturday there have been "unofficial" discussions between the Afghan government and the Taliban.
Helali's comments came a day after the top commander of U.S. and NATO forces in Afghanistan, U.S. General David Petraeus, said NATO was facilitating the safe passage of Taliban leaders to Kabul.

The Taliban has not commented since Wednesday, when it categorically denied any contact with the Afghan government.
