CAIRO: A train went off the tracks just south of Egypt's capital, Cairo, on Wednesday, killing four people, according to the head of the country's ambulance service.

Ahmed al-Ansari said that 25 people were injured in the accident in the al-Ayat area. Earlier in the day, al-Ansari had said that three people were killed but one of the injured later died of his injuries.

The cause of the accident was not immediately known but railway officials said the first three cars of the train, which was traveling to the southern city of Aswan, went off the tracks. The accident halted train services from Cairo to provinces south of the capital.

It comes during one of the busiest travel times of the year, when millions of Egyptians leave Cairo and other big cities to head to their hometowns and villages for the Eid al-Adha, a major Muslim holiday that begins on Monday.
