In another incursion, Chinese troops intruded into the Chumar sector in Ladakh -- the same area which had sparked off tensions in April--and smashed some bunkers besides cutting wires of cameras installed at the border post.

Official sources said today the intrusion took place on June 17 when the troops of China's People's Liberation Army(PLA) entered Indian territory in the Chumar sector and started vandalising the observation bunkers besides cutting the wires which overlook the Chinese territory.

Chumar, located 300 km from Leh, has always been an area of discomfort for the Chinese troops as this is the only area along the Sino-Indian border where they do not have any direct access to the Line of Actual Control(LAC).

The 21-day face-off between the two sides in the remote Daulat Beg Oldi (DBO) sector on April 15 was triggered by construction of an observation tower in Chumar division which had to be subsequently dismantled by the Army on May 5 before the crisis was defused.
