The number of people using the Eurostar fell in the first quarter of the year as travellers "remain cautious" following terrorist attacks in Paris and Brussels.
The company reported a 100,000 fall in passengers to 2.2 million in the first three months of the year, compared with the same period last year. Revenues also fell 6% to £201m.
However, Eurostar said there had been a surge in demand for tickets in recent weeks with the Euro 2016 football tournament, held in France, edges nearer. In particular, the opening game - France vs Romania on 10 June - has seen the biggest rise in demand for tickets. Eurostar expects around 500,000 to travel to host cities, including Paris, Lyon, Lille and Marseille among other, via its services.
Speaking to the BBC, Eurostar chief executive, Nicolas Petrovic, said British passengers had started travelling to Paris and Brussels again "quite quickly" after the attacks.
However, concern among US and Asian travellers has remained quite strong.
Mr Petrovic said: "People coming form North America and South East Asia, particularly Japan, are fearful of coming to Europe at all. They don't really understand what's going on and would rather go elsewhere altogether."
"Hopefully next year international visitors will come back," he added.
