Nepalese army officials say the kingdom's Maoist rebels killed four people and injured at least 11 in two separate attacks Monday.

Officials say three soldiers and one civilian died in a clash at an army checkpoint about 30 kilometers from the capital, Kathmandu.

Police said at least 11 people were injured when a bomb exploded in a market in Pokhara, about 200 kilometers west of the capital.

On Sunday, government troops killed at least 16 Maoists following a rebel assault on a security patrol in western Nepal. At least five soldiers were wounded.

Rebel attacks have increased since The Maoists broke a ceasefire last month. They are fighting to establish a single party communist republic. About 13,000 people have been killed in the fighting.
