At least four people have died after a boat carrying more than 20 passengers, including tourists, sank in strong winds on Lake Maggiore in northern Italy.
The boat overturned on Sunday evening between the towns of Sesto Calende and Arona.
Five people were taken to hospital after being rescued, reports BBC.
Italian media say the boat's passengers were British, Italian and Israeli.
Attilio Fontana, president of the Lombardy region, said the "very serious incident" was due to bad weather.
The boat was 16m (52ft) long and had been hired by tourists, he said.
According to Italian media, the boat had been carrying about 25 people who were celebrating a birthday when a storm developed over the lake, later turning into a "small hurricane".
The boat capsized and sank soon afterwards.
Everyone onboard went into the water, but many of the passengers swam ashore or were rescued by other boats.
Rescue divers and a helicopter scrambled to help with the search at the lake's southern end, and several ambulances and an air ambulance attended the scene.
A video shared by firefighters showed chairs and other debris floating in choppy waters.
Lake Maggiore - on the south side of the Alps - is shared by Italy and Switzerland and is a popular destination for tourists.
