Israel's Counter-Terrorism Bureau (CTB) has warned its nationals against travelling to India saying that the threat of possible attacks against them has become "significantly more severe" since a stark travel advisory issued last month.
The bureau said there was a "concrete" threat of attacks on Chabad centres and synagogues throughout India, including Goa, as well as on sites frequented by Israelis and Westerners.
Israel's Channel 10 reported that the new warning was based on new intelligence received by Israeli officials indicating that a Global Jihad group had teamed up with the Pakistani terror cell responsible for the 2008 Mumbai massacre and was planning an attack.
A Chabad house was one of the targets of the 2008 Mumbai attacks.
The CTB strongly advised Israelis in India to avoid places that are not visibly secured with armed guards.
The bureau also issued a separate advisory against visiting the Kashmir region in the north of the country.
A similar warning issued in September said a Pakistani terror organisation affiliated with al-Qaida, and responsible for the attacks in Mumbai last November, was planning to carry out a string of attacks throughout the Indian subcontinent.
That warning said while all Westerners in India were in peril of being targeted, Israelis and places where they usually congregate in large numbers were in more serious danger.
