The U.S.-led coalition in Afghanistan says its forces have killed at least 24 militants during two separate battles.

In a statement Friday, the coalition says Afghan and U.S. forces killed at least 12 militants, after an attack on a coalition base in the Shahidi Hassas district of southern Uruzgan province on Thursday.

Also Thursday, the coalition says its forces killed another 12 militants while on patrol in eastern Paktika province.  U.S. officials say troops came under attack, while looking for militants who were transporting foreign fighters between the two countries.

On Thursday, the U.S.-led coalition said its troops killed more than 100 militants during four days of fighting in southern Afghanistan.

Also, officials say three civilians - a woman and two children - were killed late Thursday after German and Afghan forces fired at a car that failed to stop at a checkpoint in the northern province of Kunduz.
