At least 26 people were killed Sunday night when a cargo train slammed into two cars south of Cairo, Egyptian state-run media reported.

Another 28 people were injured, Egypt’s head of emergency services told the Egynews website.

It was not immediately clear what led up to the collision.

Deadly train crashes are not uncommon in Egypt.

In January, train cars filled with Egyptian security force recruits hopped the tracks and crashed in Giza, killing at least 19 people and injuring some 107 others.
