At least 26 people were killed and 85 injured after two trains collided near the Greek city of Larissa on Wednesday.

The collision happened shortly after 11 a.m. local time, when a passenger train collided with a freight train at a junction near the town of Adendro. The passenger train was en route from Athens to Thessaloniki, and the freight train was travelling from Kalampaka to Volos.

The collision caused a massive fireball and plumes of black smoke to rise into the sky, and the ensuing carnage has been described as “horrific” by local officials.

The cause of the crash is still under investigation, but authorities have said that the passenger train was travelling above the speed limit when the crash occurred.

At least 60 people were injured, many of them seriously, and were taken to hospitals in Larissa and Thessaloniki.

Greek Prime Minister Kyriakos Mitsotakis expressed his condolences to the families of the victims and said that the government would be providing assistance to those affected.

The accident is the latest in a series of deadly train crashes in Greece, which has one of Europe’s oldest railway systems. In 2017, three people were killed and nine injured in a collision near Athens.
