Five people died and 38 people were injured Monday when a public transportation bus overturned on Egypt's Koraymat Road in Upper Egypt's Beni Suef governorate, the health ministry has said.

Security sources put the death toll at nine. 

Initial investigations show that an exploded tyre forced the driver to swerve into the opposite lane before the bus hit a barrier and then dropped from a height of three metres.

Fourteen of the injured who were transported to Beni Suef public hospital have since been discharged, with one still undergoing treatment. The 23 others were transported to Beni Suef university hospital and are still receiving treatment.

Most of the victims are from Al-Wadi Al-Gedid, Sharqiya, and Cairo, according to media reports.

Koraymat highway has seen many deadly accidents since it opened in 2011. The highway is known for lacking proper lighting, police checkpoints, and emergency medical services.

Meanwhile in Beheira, a 25-year old woman and her three-year-old son died, and four were injured including the driver, when a car overturned on Kom Hamada-Tawfiqeya road in Giza.

The car's back tyre exploded, causing it to hit a barrier on the side of the road.
