India News: Reliance Industries chairman Mukesh Ambani will now get 'Z' category protection, with the Union home ministry approving an armed squad of CRPF commandos for his proximate security less than two months after a threat letter, purportedly from the Indian Mujahideen, was hand-delivered at his office in Mumbai.

The letter is said to have threatened a terror attack at his Antilia residence at Altamount Road in south Mumbai.
