At least 10 people were killed in a bomb attack on a popular market in northeast Moscow, which Moscow Prosecutor Yury Syomin said was more likely down to a turf war between commercial groups rather than terrorism.
"There is a high threat from terrorism in Russia, including suicide bombings in public places," the Foreign Office said. "The risk of terrorism in Moscow could rise quickly in relation to any escalation of violence in Chechnya."
The Foreign Office advises against all travel to the North Caucasus republics of Chechnya, Ingushetia and Daghestan, where a number of fatal attacks have happened in the last few months. It also advises British nationals to avoid a number of areas in the east and south of the Stavropol Territory that border on Daghestan and Chechnya. The office also advises against all but essential travel to North Ossetia, Karachayevo-Circassia and Kabardino-Balkaria, including the Mount Elbrus area.
The Foreign office also recommends British tourists in Russia - and there are about 215,000 visitors each year - to remain vigilant in all public places, including tourist sites and crowded places, particularly at open-air events and markets, where access is not controlled.
