US joins warnings over potential Isil terror at the Euros
The US has become the latest government to issue a warning that the Euro 2016 championship in France could be a target for terrorism.
The State Department is warning Americans visiting Europe this summer about the potential for terrorist attacks.
The travel alert issued last night said that major sporting events, tourist sites, restaurants and shopping centres were possible targets.
France is hosting soccer's European Championship, as well as cycling's Tour de France, while under an extended state of emergency following November's Isil attacks in Paris.
The State Department tells US citizens to be vigilant in public places or when using mass transport. They should also be prepared for additional security screening and unexpected disruptions.
It follows remarks by French spy chief Patrick Calvar, who also warned that Isil terrorists were gearing up for a campaign of bomb attacks on large crowds.
He spelled out "a new form of attack... characterised by placing explosive devices in places where there are large crowds and repeating this type of action to create a climate of maximum panic".
Upwards of 70,000 Irish fans are expected to travel to France for Euro 2016, despite the FAI receiving less than 40,000 tickets.
But Mr Calvar warned: "Clearly, France is the most threatened and we know that Daesh (Isil) is planning new attacks."
