The U.S. military says coalition forces in Afghanistan have killed 22 militants in a series of clashes throughout the country.

Officials said the coalition's ground and air assaults took place Monday in southern and eastern Afghanistan.  They said one operation targeted a Taliban network in Kapisa province, killing 18 insurgents and one Taliban commander.  

The military also said they killed another Taliban commander and two insurgents in two raids in the Kandahar and Zabul provinces.

Officials did not mention any casualties among coalition troops.

Violence has risen in Afghanistan as militants have made a comeback after their initial defeat following the U.S.-led invasion in 2001.
