Union Defence Minister Rajnath Singh on Wednesday welcomed the Rafale fighter jets after its landing in India and gave a stern warning to China and Pakistan saying that if anyone should be worried about the Indian Air Force's (IAF) new capability it should be those who want to threaten the territorial integrity.

The first batch of India's five incoming Rafale fighters landed at the Ambala Air Force base at around 3.14 pm amid a ceremonial welcome and unprecedented security. The jets took off from the Merignac airbase in French port city of Bordeaux on July 27 and covered a distance of 7,000 km with air-to-air refuelling and a single stop in the United Arab Emirates.

Taking to micro-blogging site Twitter, the Defence Minister said, "I would like to add, if it is anyone who should be worried about or critical about this new capability of the Indian Air Force, it should be those who want to threaten our territorial integrity."

Singh also took a jibe at the Congress saying that the fighter jets were purchased when they fully met the operational requirements of the IAF and the baseless allegations against the procurement have already been answered. "The Rafale jets were purchased when they fully met the operational requirements of the IAF. The baseless allegations against this procurement have already been answered and settled," he tweeted.
