International and Afghan forces targeted militants in Afghanistan, one day after five NATO and U.S. troops were killed in an attack in the country's east.

The U.S. military says coalition and Afghan forces killed five militants during operations in the southern province of Helmand on Saturday.

A statement Saturday says Afghan-led troops were conducting a routine patrol, in Nahr Surkh district, when they came under attack from militants.  

Afghan officials say an air strike in neighboring Kandahar province killed at least six militants early Saturday.

In other violence, the Afghan Interior Ministry says a roadside bomb killed the Farsi district police chief and his bodyguard in the western province of Herat Saturday.  Six other police officers were wounded in the attack.

On Friday, NATO and U.S. officials said insurgents killed three U.S. and two Latvian soldiers in eastern Afghanistan.

A top Taliban commander warned earlier this week that militants are planning to unleash a wave of ambushes, suicide attacks and bombings against international troops.
