The U.S. military in Afghanistan says fighting in two southern provinces has left four suspected militants dead and two Afghan police wounded.

A U.S. military spokesman Lieutenant Colonel Jerry O'Hara says three insurgents were killed and two Afghan police officers wounded during a clash Friday in the Deh Rawood district of Uruzgan province. One fighter was captured, along with a light machine gun and a rocket-propelled grenade.

The spokesman said that, on the same day, south of Kabul, one militant was killed when a group of insurgents attacked a U.S. and Afghan military convoy.

There has been an upsurge of violence in Afghanistan ahead of the September 18 parliamentary elections. Hundreds of people have died in militant-related violence so far this year.
