British tourists travelling to India have been warned to be on their guard amid reports of a terrorist plot against Westerners.
Pakistani militants are planning a wave of strikes at tourist sites including Delhi, Mumbai and Goa in the south, according to reports.
The Foreign Office updated its travel advice - advising travellers to be extra vigilant on days of national significance including Diwali on October 17.
The level of threat remains unchanged at "high".
The warning follows news that
Israel has warned its citizens to avoid the country completely.
According to Israeli media - including the country's Channel Two - intelligence sources believe al Qaeda operatives are planning to target Western and Jewish tourists.
The plots are said to be styled on the attacks in Mumbai last November when 10 gunmen went on the rampage.
Mumbai's
anti-terrorism force said they had been liaising with Israel over the intelligence.
But force chief K.P. Raghuvanshi said: "We are regularly in touch with them, sharing intelligence and news about any threats. But we have not heard anything specific about the latest alert."
A Foreign Office spokesman said the
terrorism threat remained high.
The FCO website's travel page advises: "You should take care to be extra vigilant in your movements in the lead up to and on days of national significance."
India was put on high alert this week after intelligence reports said Pakistan-based militants were trying to sneak into India through the Kashmir border.
At least 60 militants have been shot dead on the border in the last 12 months, Indian officials said.
"Security in any case has been very tight for tourists and as a result there has not been a single terrorist attack on them in the last several months," Gopal Pillai, a top interior ministry official said.
