France warns travellers of risk in Britain
France on Tuesday called on its nationals to be "extremely vigilant" while taking public transport and visiting tourist sites in Britain after London ranked as high the risk of an attack as high.
The recommendation was included in travel advice published on the French foreign ministry's website.
"British authorities believe that the terrorist threat level is very high in the United Kingdom and the risk of an attack highly probable," the ministry said.
"It is recommended to be extremely vigilant in public transports and the most visited tourist sites."
Britain updated its travel advice for France and Germany on Sunday, warning there was a "high threat of terrorism" as it backed a similar US alert about possible attacks across Europe.
The move came shortly after the US State Department issued a travel alert for Europe, warning of "the potential for terrorist attacks" and urging Americans to take precautions in public places and transport systems.
The alerts follow news reports in the past week saying Western intelligence agencies had uncovered an Al-Qaeda plot to launch commando-style attacks in Britain, France, Germany and the United States.
