Football fans travelling to Euro 2016 have been warned to remain "vigilant at all times" in the face of the terrorism threat.
Updated advice from the Foreign and Commonwealth Office highlights stadiums, fan zones, other venues broadcasting the tournament and transport hubs and links as potential targets for atrocities.
British counter-terrorism officers are playing "a key part" in planning against attacks that may target the tournament and a team from the UK has travelled to France and is working with police and intelligence services there to assess possible threats.
