At least 32 people have been killed and 165 injured in a train crash in central Egypt, officials say.
Two carriages derailed and overturned when two passenger trains collided near the city of Tahta, Sohag province.
Emergency brakes were activated on the train in front by “unknown individuals”, causing the train behind to crash into it, the country’s railway authority said.
President Abdul Fattah al-Sisi pledged tough punishment for those 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.
The incident happened about 365km (227 miles) south of the capital Cairo.
One of the trains was travelling between the southern city of Luxor and the Mediterranean port of Alexandria, while the other was travelling between the capital Cairo and the city of Aswan in southern Egypt.
More than 70 ambulances were sent to the crash site to take the injured to hospitals.
