A bus carrying foreign tourists including Ukrainians crashed near the Italian city of Venice when it fell from an elevated street Tuesday, killing at least 21 people and injuring 18 others, authorities said, writes Euronews.

Four of the injured were in serious condition following the accident in the Mestre borough, on the mainland opposite the historic old city of Venice, said Renato Boraso, a Venice city official. Two of the dead were children, Venice prefect Michele Di Bari said.

According to local media, the bus fell a few metres before crashing close to Mestre’s railway tracks, where it caught fire. Emergency crews were on the scene. Premier Giorgia Meloni expressed her “deepest sorrow” after the crash.
