India airports across the country were placed on high alert after the country’s Bureau of Civil Aviation received an e-mail warning that on 6 December, terror groups might strike at airports located on coast of the western Gujarat state. The civial aviation department also issued a hijack warning Thursday morning for Delhi, Bangalore and Chennai airports. Indian media reported that according to government sources about a dozen sleeper cells are likely to be activated. Meanwhile, reports of gunshots Thursday night at New Delhi’s international airport sent seuciryt scrambling, but police have since said there is no evidence of any gunfire. “Everything is normal,” Udayan Bannerjee, head of the paramilitary Central Industrial Security Force, which is responsible for airport security, was quoted in an AFP report. Bannerjee said personnel had heard “two sounds that appeared to them as gunshots” and sounded the alarm, causing a lockdown at the airport that lasted about 40 minutes. “There were no eyewitnesses to any gunshots and no rounds were recovered,” he said, adding all airport operations were back to normal. Airports in India, including those in Bangalore, Chennai, Hyderabad, Kolkata, Mumbai and New Delhi, have been on high alert since yesterday after Defense Minister A.K. Antony ordered the armed forces to be on guard against “any terror strikes from the air,” according to the report.
