Football fans travelling to France have been warned to be on their guard against terrorists "at all times"
Updated advice from the UK Foreign and Commonwealth Office (FCO) highlights stadiums, fan zones, venues broadcasting games and transport hubs and links as potential targets for atrocities.
It tells fans: "You should be vigilant at all times, especially in areas hosting Euro 2016 events, and follow the advice of local French authorities."
The warning comes after officials in Ukraine revealed they had arrested a Frenchman who was plotting a series of bloody strikes in his homeland, although the FCO says the two are not connected.
A spokesperson for the UK Foreign Office said: "We have updated the travel advice to provide further information for fans on the risk of terrorism in France as they start to travel for Euro 2016.
"This is consistent with the advice we have already issued for France and is not in response to a new or specific threat."
Yesterday it was revealed that a Frenchman was arrested in Ukraine in late May carrying an arsenal of weapons.
Speaking on Newstalk earlier, the Irish Times France correspondent Lara Marlowe said everyone in France heaved a “big sigh of relief” when it was discovered that the 25-year-old man was an extreme right-wing activist and “not a jihadist”.
Grégoire M - who is from a farm in tiny village in Eastern France - left for Ukraine last December.
He told Ukranian authorities he was there to help refugees and assist the armed groups who were fighting the Russian separatists in the East, however Marlowe told The Pat Kenny Show it has become apparent that he was “more interested in buying weapons”.
Ukraine security services said he had planned to carry out 15 separate attacks on Euro 2016 with a mosque, synagogue and tax collection office as some of the potential targets.
The frenchman was arrested on May 21st, and Marlowe explained that Ukrianian officials had initially planned to “keep it secret until after Euro 2016, but some leak forced them to reveal it”.
Lara Marlowe also added: “It does tell you a bit about the state of mind in France, that they’re relieved when they find out he is not part of Islamic State and is just a right-wing ‘loony’”.
In Ireland, the Department of Foreign Affairs advises those visiting France this summer to "exercise a high degree of caution" and to be "vigilant in public places and follow the advice of the local authorities".
