At least 28 people were killed when two trains collided in Egypt, with rescue workers still trying to free passengers. More than 80 people were also injured in the crash in Alexandria, Mohamed Abu Humus, head of the ambulance service in the northern city, said by phone on Friday. A train coming from Cairo ran into another arriving from Port Said, he said. Authorities were trying to lift the wreckage to save people trapped inside, Major General Fuad Al-Ghunaimi said. Deadly train crashes are relatively common in Egypt. In 2012, a train crashed into a nursery school bus, killing 52 children. A year later, 19 army conscripts were killed when a train derailed near Cairo. The Public Prosecution Office ordered an investigation into Friday’s incident in Alexandria, the state-run Ahram Gate reported.
