The Nepalese army says its forces have killed at least three suspected Maoist rebels who attacked an army patrol.
The clash occurred Saturday near Belbari village some 500 kilometers east of Kathmandu. The rebels were gunned down when they tried to toss grenades at the troops.
Last month, the Maoists declared a unilateral three-month ceasefire in an effort to increase their contacts with the Himalayan kingdom's mainstream political parties.
Maoist guerrillas have been fighting for nearly 10 years to overthrow the Nepalese monarchy. Their leader, a man known as Prachanda, said the ceasefire was a gesture intended to foster talks on forming a united opposition against King Gyanendra.
Clashes have increased since February when the king seized all powers. He said the move was necessary to quell the insurgency, which has claimed more than 11,000 lives.
