KABUL – At least 29 militants, including two commanders, have been killed over four days of intense fighting aimed at protecting supply routes through northern Afghanistan, the Interior Ministry said Sunday.

Elsewhere, a foreign soldier was killed by a roadside bomb in southern Afghanistan on Saturday, NATO said, the third foreign death that day following an earlier announcement of the loss of two Dutch marines in the southern province of Uruzgan. The third soldier’s nationality and other details of the incident were being withheld pending family notification, it said.

So far this month, 24 foreign soldiers have died in Afghanistan, where foreign troop levels are climbing toward 130,000 in a push to cripple the resurgent Taliban insurgency. An Afghan policeman was also killed during mine clearance operations in the southern province of Kandahar, the ministry said.
