Three Army personnel were killed on Thursday and four injured when suspected NSCN rebels ambushed their vehicle in Arunachal Pradesh's Tirap district bordering Nagaland.
The ambush on the last of the four vehicles of the convoy took place around 6 am at Tupi village along Khonsa-Longding road, Tirap SP Ajit Kumar Singla said.
The personnel of the 4 Rajput Regiment were on their way to the camp at Longding in the morning after a night halt at Khonsa, about 530 km east of Itanagar.
"They were coming from Tinsukia in neighbouring Assam in four vehicles. Most of the personnel, who were on leave, were returning from their home state," Singla said.
The injured have been rushed to Army hospital.
However, there were no casualties on the other side, the SP said.
Army sources said the three personnel were killed on the spot.
They said it is suspected that one of the two factions of NSCN -- IM and K -- was behind the ambush.
The NSCN faction led by S S Khaplang had recently called off the ceasefire with the government.
