Government has received inputs about terrorists' plans to carry out a 9/11-type aerial attack on targets in India, Air chief Fali Homi Major said on Thursday.
"This (report about terrorists carrying out possible aerial attacks) is based on a warning, which has been received (by the government) and we are prepared as usual," Major told reporters after laying a wreath at Amar Jawan Jyoti at India Gate on the occasion of Navy Day.
He said the issue was discussed during the meeting of three service chiefs with Defence Minister A K Antony on Wednesday at South Block.
"The issue was discussed in yesterday's meeting," he said.
After receiving inputs from intelligence agencies about possible aerial strikes by terrorists, airports in Delhi, Bangalore and Chennai were put on high alert last night as the reports suggested that terrorists could have sneaked into India to carry out strikes on the anniversary of the demolition of the Babri Masjid.
Defence Minister A K Antony had also on Wednesday warned the armed forces about the possibility of terror attacks from airborne platforms similar to the 9/11 attacks in the US.
In the meeting, Antony called for greater coordination among security and intelligence agencies so as to make the intelligence inputs actionable.
Antony wanted tightening of vigil along India's coastal, land and aerial frontiers to prevent terror attacks in future.
