New Delhi. As part of tightening security measures along the Sino-Indian border, Indian Air Force choppers were spotted flying at Chinyalisaur airstrip of Uttarkashi district, a day after India and China showed first signs of de-escalation of tension by withdrawal of troops along the Line of Actual Control (LAC).

The sorties were held on July six evening amid tight security arrangements by Indian Army personnel near the airstrip which is used as the advance landing ground by IAF.

According to district officials, two IAF’s Mi17 helicopters were seen flying at the Advance Landing Ground in Chinyalisaur airstrip.

“The helicopters landed and took-off at least five times. They also flew near the border for inspecting security,” said an official of the district administration not wishing to be named.

Superintendent of police (SP) Uttarkashi Pankaj Bhatt confirmed the air force’s activity and said that two IAF choppers landed at the spot.

Earlier in June, AN-32 aircraft of the air force had also landed there as part of an exercise.

Security has been tightened near the Indo-China border in Uttarakhand by the armed forces after the clash in Galwan Valley. Border Roads Organisation has also sped up its various projects in the area.

On July 7, defence minister Rajnath Singh reviewed the progress of BRO projects near LAC and LOC in which he also sought the progress report of those in Uttarakhand.
