Israel’s anti-terrorism directorate issued a travel warning for India, citing an immediate threat of attack to Western and tourist targets.
The south-west of the country is particularly at risk, the warning said.
It continued: “A particular emphasis should be put on events in the coming days in connection with beach and club parties celebrating the New Year where a concentration of tourists will be high.”
The statement recommended that tourists avoid participation in such parties. It also called people to contact their relatives in India and tell them of the threat.
In addition, it recommended avoiding markets, festivals and crowded shopping areas.
Unusually, the warning was published on a Friday evening in Israel, after the start of the Jewish Sabbath, when government offices close for business.
The directorate did not say what prompted the warning but it comes as Europe is on high alert since a truck crashed into a Christmas market in Berlin, killing 12.

The warning includes the coastal state of Goa.
It is a popular destination for Brits for beach holidays.
Other popular tourist hotspots in India include the Taj Mahal in Agra and the Red Fort in Delhi.
“There is a high threat from terrorism”
The UK Government is calling on travellers to be on high alert.
The Foreign Office said: “There is a high threat from terrorism. Terrorist attacks are carried out by a number of terrorist and insurgent groups including Lashkar-e Tayyiba, Jaish-e Mohammed and the Indian Mujahideen.
“While the main focus of attacks are against Indian interests, terrorists have previously targeted places visited by Westerners including public places like restaurants, hotels, railway stations, markets, places of worship, festivals and sporting venues.”
