The Foreign Office is advising British tourists in Paris to be especially vigilant while security is ramped up around the city.  The shootings that killed 12 people at the Charlie Hebdo office on January 7, were followed by an attack by a gunman who shot and injured people in Montrouge, Paris, yesterday. Today, more of the city is under siege with another shoot out involving hostages at a supermarket in Porte de Vincennes, in the east of the city, and more gunmen holed up in an industrial complex in the north east.  Metro trains are currently not stopping at the Porte de Vincennes station around which there is an exclusion zone. Due to police forces on the streets about 15km from Charles de Gaulle airport in the north, landings on the airport's north runway were limited this morning to allow helicopters to fly over the area. This caused 30 minute delays to Air France flights but the situation has now improved, an Air France spokesman said.  “There is a high threat from terrorism,” the FO advised British travellers on its website. “Attacks could be indiscriminate. You should be especially vigilant at this time and follow the security advice issued by the French authorities.”  The French tourist board said that a new meeting of an inter-ministerial crisis group will take place later today, to review the measures that have been put in place in the region, which is on an "attack alert" level of security.  In a statement released yesterday it hoped that “British travellers will continue their visits to Paris and thereby show solidarity and not let these horrible attacks defeat us. As it has been said elsewhere, Fraternité is as important as Liberté.  “Travellers should act responsibly, take ‘extra care’ and follow any security advice from the French authorities.”  The inter-ministerial crisis group yesterday decided to deploy six republican (military) companies and gendarmerie squads as back up to the 10 already present in the capital.  The Paris tourist board told Telegraph Travel that “all sites, notably tourist attractions that require extra security are part of the plan.”  It added that it “unites with the Paris city council authorities to condemn this horrifying attack and to assure visitors that everything will be done to ensure their safety."
