ATHENS — "Deeply saddened by the tragic railway accident in Egypt," the Greek foreign ministry posted on Twitter on Monday.

"Our thoughts are with the families of the victims and with the injured. We express our full solidarity to the people and to the government of our friend Egypt," it added.

A passenger train derailed Sunday north of Cairo, killing at least 11 people, Egyptian authorities said. It was the latest of several rail accidents to hit the country in recent years.

Four train wagons ran off the railway at the city of Banha in Qalyubia province, just outside Cairo, the railway authority said in a statement. Videos on social media showed wagons overturned and passengers escaping to safety along the railway.

The train was travelling to the Nile Delta city of Mansoura from the Egyptian capital, the statement said.

The Health Ministry said in a statement that besides the dead, at least 98 people were injured, with most of them suffering from broken bones, cuts and bruises.

At least 60 ambulances were sent to the scene and the injured were taken to nearby hospitals, the ministry added.

Salvage teams could be seen searching for survivors and removing the derailed wagons. It was not immediately clear what caused the train to derail. Prosecutors said they were investigating the causes of the crash.

The state-run Ahram daily reported that authorities have detained at least 10 railway officials, including the train driver and his assistant, pending an investigation into the crash.

At Banha University hospital, people lined up to donate blood for the crash victims. Families were also present looking for loved ones who had been travelling on the train.

“We were surprised by the strain speeding up,” said Tarek Gomaa, one of the injured. “We found ourselves on top of each other.”
