"There is a threat perception from such agencies but the nation is prepared for it," he said when asked about the al-Qaeda threat to start operations in India.
He was talking to reporters on the sidelines of a seminar on the role of Air Force in the 1965 war with Pakistan.
US media and intelligence agencies had said yesterday that al-Qaeda has established a new branch to wage jihad in India, revive its caliphate and impose sharia in the Indian sub-continent.
The creation of the group called "Qaedat al-Jihad in the Indian Subcontinent" was announced by As Sahab, al-Qaeda's official media outlet, in a lengthy video posted on social media outlets.
Al-Qaeda is active in Afghanistan and Pakistan, but the group's leader Ayman al Zawahiri said "Qaedat al-Jihad" would take the fight to India, Myanmar and Bangladesh.
Security agencies feel the video could be an attempt by al-Qaeda to carry out fresh recruitments in the sub-continent as it stares at diminishing influence vis-a-vis the ISIS.
