NEW DELHI, Dec. 8 (Xinhua) -- India's Chief of Defense Staff (CDS) General Bipin Rawat and 12 others including his wife were killed and one was injured on Wednesday in a helicopter crash in the southern state of Tamil Nadu, officials said.
"Deeply anguished by the sudden demise of Chief of Defence Staff Gen Bipin Rawat, his wife and 11 other armed forces personnel in an extremely unfortunate helicopter accident today in Tamil Nadu. His untimely death is an irreparable loss to our armed forces and the country," India's Defense Minister Rajnath Singh wrote on social media.
"General Rawat had served the country with exceptional courage and diligence. As the first Chief of Defence Staff he had prepared plans for jointness of our armed forces," he said.
The helicopter crashed at Coonoor area of Nilgiris district, about 538 km southwest of Chennai, the capital city of Tamil Nadu.

"My heart goes out to the families of those who lost their loved ones in this accident. Praying for the speedy recovery of group captain Varun Singh, who is currently under treatment at the Military Hospital, Wellington," Singh wrote.
Singh visited the residence of Rawat in New Delhi to express solidarity with his family members. Singh has also reportedly briefed Indian Prime Minister Narendra Modi about the incident.
Reports said he is likely to brief parliament, which is currently in session, on the crash on Thursday.
