Intelligence sources say al-Qaeda plans to carry out attacks in the UK, France and Germany
The US government has warned its citizens in an official travel advisory to be vigilant travelling in Europe, amid fears of an al-Qaeda commando-style attack.
The state department advised Americans to take care while in tourist areas.
The department did not specify a country, issuing the updated guidance for the whole of Europe.
Security sources have warned of an al-Qaeda plan to send teams of gunmen to crowded places to kill civilians.
They said cities in the UK, France and Germany were thought to be targets for the militants, in attacks analysts feared could be similar to the 2008 atrocities in Mumbai.
After intelligence details of the plot had been leaked to the US media last week, officials said that the plan had not been stopped but that an attack was not expected to be carried out imminently.
The state department alert said European governments had "taken action to guard against a terrorist attack", but that "terrorists may elect to use a variety of means and weapons and target both official and private interests".
However, US citizens were not told to avoid travelling in Europe, and the advisory is less serious than a travel warning. Even so it may well have a devastating effect on travel given the current shaky tourism recovery.
After the US alert was issued, the UK confirmed it had updated its guidance for travellers in Germany and France, warning of a "high threat" from terrorism.
