A Pakistani terror organization affiliated with al-Qaida and responsible for the attacks in Mumbai last year is planning to carry out a string of attacks throughout the Indian subcontinent, it warned.
The warning said that while all westerners in India are in peril of being targeted, Israelis and places where Israelis usually congregate in large numbers are in more serious danger.
The bureau asked all Israelis in India to steer clear of places where Western tourists are found in large numbers. It put a special emphasis on Chabad houses, which are popular with Israeli tourists, especially during the High Holidays.
The bureau rated the threat as "imminent and concrete," and emphasized the Jammu and Kashmir regions in India's North.
Thursday's warning was unusual, as India is a friendly country and there are tens of thousands of Israelis in India at any given time.
Arab countries like Jordan, Egypt - including the Sinai Peninsula - and Morocco are regularly mentioned in Counter-Terrorism Bureau statements, especially during and following Israeli military operations.
