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. French authorities said the boat left France on Monday night.

Overnight five people on board the vessel required rescue, while 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 services, 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, French authorities decided not to intervene further at that stage. But on Tuesday morning the engine caught fire and the vessel's integrity deteriorated very rapidly.

Rescue boats went to the scene from France and the UK, including the RNLI Eastbourne lifeboat and the UK Border Force vessels BSC Contender and BSC Courageous. Two French boats rescued 103 migrants and the British boats rescued 54.

All of them are being taken to Boulogne-sur-Mer for treatment, where they are expected to arrive at port on Tuesday afternoon. Earlier, the UK Coastguard confirmed that a vessel caught fire in the French search and rescue region, with UK vessels and a lifeboat assisting.

Between 1 January and 1 August 2026, a total of 14,526 people crossed the English Channel by small boat from France. This was down by 43% on the same period the previous year. These crossings have become the most common way for people to be detected entering the UK illegally since 2020.

Nearly all those who arrive by small boat claim asylum. Under international law, this means they are allowed to stay in the country while their asylum application is considered. Small boat arrivals made up 42% of asylum applications between April 2025 to March 2026.

Boats that arrived in the UK from 2 August 2025 to 1 August 2026 carried an average of 67 people. This has more than doubled since 2021. Experts say overcrowding in boats makes crossings significantly riskier.

At least 84 people died while attempting to cross the Channel in 2024, according to the United Nations. When looking at the scale of small boats crossings, the number of these arrivals is about 5% of the size of total immigration into the UK from January 2025 to December 2025.

The government has pledged to dismantle the gangs behind these crossings in order to reduce the numbers. People from Eritrea accounted for 18% of all arrivals from April 2025 to March 2026.

In the latest figures covering January 2025 to December 2025, at least 2,000 people who arrived by small boat were found to be potential victims of human trafficking or other forms of modern slavery, according to the Home Office. Another 4,535 people were detected entering the UK without permission via other methods including hiding in vehicles, travelling on ferries or through airports.

There are also individuals who arrive legally, for example via a work or study visa, and then overstay their limit.
