At least 32 people were killed and 108 injured when two trains collided in central Egypt on Friday, health ministry officials said, APA reports quoting Reuters.
"Unknown individuals" triggered the emergency brakes on one of the trains causing it to stop, the rail authority said. The second train, which was travelling in the same direction, crashed into the first from behind, it added.
Pictures showed train carriages derailed, several of them badly damaged, above a channel of water, as crowds looked on.
The public prosecutor's office said it had ordered an investigation into the crash which took place close to the Nile-side town of Tahta, about 365 km (230 miles) south of Cairo.
Egypt's President Abdel Fattah al-Sisi mourned the victims of the crash in a statement posted on his official social media and said those responsible would be punished.
