Border Force pictured escorting migrants to the UK after being rescued in the Channel in March More than 150 migrants have been rescued after the boat they were using to cross the Channel caught fire on Tuesday morning, French authorities have said. The boat was attempting to cross to the UK when its engine caught fire, according to the French maritime prefecture of the Channel and North Sea. It said 157 people have been rescued and are being taken to port in Boulogne-sur-Mer. There are no reports of anyone having been injured or killed. It comes just a day after Prime Minister Andy Burnham pledged his government will be "relentless" in curbing the number of people arriving in the UK on small boats. Overnight "five people on board the vessel required rescue... the remaining people on board refused the assistance offered by the French patrol boats", the French maritime prefecture said. "Determined to reach the United Kingdom, migrants crossing the Channel in small boats refused assistance offered by French emergency service, accepting it only in situations of extreme emergency," it said in a statement. Because of the "structural fragility" of boats used to cross the Channel, it said they decided not to intervene further at that stage.
