At least 21 people have died after a city bus carrying tourists to a campground crashed off an overpass near Venice in northern Italy and caught fire, officials said.
The coach veered off the road and fell close to railway lines in the district of Mestre, which is connected to Venice by a bridge, Italian news agencies and television reported.
The cause of the crash was still unclear.
Officials said the vehicle fell 30 metres onto electricity lines and caught fire at around 7.45pm local time.
"It's an apocalyptic scene. I am speechless," Mayor Luigi Brugnaro posted on X, formerly known as Twitter.
The head of the local firefighters said the victims so far identified were Ukrainian tourists.
Italian news agency ANSA said Germans as well as Ukrainians were among the passengers.
The city's prefect, Michele Di Bari, said he could not confirm this.
"The bus is totally crushed. The firefighters had difficulty getting a lot of the bodies out," Mr Di Bari told Sky Italia television.
He said 21 people had died, including the Italian driver and two children.
Prime Minister Giorgia Meloni expressed her condolences, saying in a statement that her government's thoughts were with "the victims, their families and their friends".
Italy has suffered a number of deadly bus crashes in recent years.
In 2017, 16 people on board a bus carrying Hungarian students died in a crash near the northern city of Verona, while in 2013, 40 people died when a bus plunged off a viaduct in southern Italy in one of the country's worst road crashes.
