NEW DELHI, June 4 - Two helicopters of the People�s Liberation Army of China hovered over Chamoli district in Uttarakhand yesterday, triggering concern in India�s security establishment about the PLA�s fourth such incursion into Indian airspace since March this year.
Official sources said the choppers, which returned to the Chinese side after about five minutes, could have carried out aerial photography of Indian ground troops during what was possibly a reconnaissance mission.
The Indian Air Force (IAF) is probing the incident, an IAF source said. The choppers were identified as the Zhiba series of attack helicopters.
On previous occasions, Chinese choppers had entered 4.5 km into Indian territory, an area that China claims as its own and recognises as Wu-Je. � PTI
