A boat carrying at least 20 tourists and crew members has overturned in a whirlwind on Italy’s Lake Maggiore.
At least two people have died and two other remain missing, according to Italian media reports.
Italy’s fire service said 19 people have been saved, with many reportedly managing to swim to shore.
Sky Italia reported that British passengers were aboard the vessel.
Rescue operations are continuing with divers, boats and a helicopter spotted at the scene.
Firefighter video showed pieces of wood floating in the lake as a helicopter flew overhead.
The whirlwind was part of a storm system that hit the northern region of Lombardy on Sunday evening, forcing delays at the Malpensa airport.
