French and British vessels saved 157 migrants after their boat caught fire while trying to cross the Channel on Tuesday, authorities in both countries said.

It is one of the largest such rescue operations reported since records began in 2018.

“A small boat caught fire on the boundary between French and British waters, forcing its occupants to jump overboard” on Tuesday morning, the prefect’s office in France’s Pas-de-Calais region said, adding no casualties had been reported.

They had left the coastal village of Veules-les-Roses in Normandy on Monday, French maritime authorities said.

A spokesman for the British coastguard said UK vessels and a lifeboat were assisting after “a vessel caught fire earlier this morning whilst in the French search and rescue region”.

The Royal National Lifeboat Institution charity said a “lifeboat launched at 6:00am today to an incident”.

In recent weeks, witnesses in France have said they have seen dinghies larger than usual cross the shipping lane, reporting they seemed to be 12 metres long instead of the usual 8 or 10 metres.

French maritime authorities have told AFP the average number of people piled on these small boats has risen — from 26 in 2021 to 65 since the start of the year.

France has long been a launchpad for migrants hoping to cross the Channel to reach Britain.

Paying smugglers thousands of dollars, people often board overloaded rubber dinghies to make the dangerous and sometimes deadly journey across one of the world’s busiest shipping routes.

More than 41,000 migrants landed on England’s southern coast last year — the second-highest annual number since 2018.

So far this year, 14 people have died trying to cross the Channel, according to an AFP tally based on official French and British sources.

At least 29 migrants lost their lives in the Channel last year, according to a similar AFP count.
