At least 32 people died and more than 60 were injured in a train crash in southern Egypt, the country’s railway authority said.
Two carriages were derailed and overturned when two passenger trains collided in the province of Sohag.
Emergency brakes were activated on the train in front by “unknown individuals”, causing the train behind to crash into it, the authority said.
Officials are investigating the cause of the crash.
Egyptian President Abdel Fattah al-Sisi said there would be serious consequences for anyone found responsible.
“Anyone who caused this painful accident through negligence or corruption, or anything similar, must receive a deterrent punishment without exception or delay,” he tweeted.
Photos from the scene show carriages overturned near a channel of water.
Egypt has seen frequent accidents on its railway system due in part to poor maintenance and lack of investment.
One of the deadliest train disasters occurred in 2002 when 373 people died when a fire broke out in carriage travelling south of Cairo.
