Military officials in Nepal say 11 Maoist rebels and two soldiers were killed during fighting at an army camp in eastern Nepal.
Officials say the rebels attacked the army camp, located 400 kilometers east of the capital, Kathmandu, late Friday.
Maoist rebels have carried out a series of attacks across Nepal since ending their four-month, unilateral cease-fire on January 2.
They have been fighting to overthrow the constitutional monarchy and replace it with a communist state since 1996. At least 12,000 people have died in the fighting.
Nepal's King Gyanendra took absolute control of the country nearly a year ago.
