Thirteen people were killed and tens of others wounded as a result of torrential trains hitting several Egyptian governorates since Thursday, the health ministry and Ahram Arabic website said.
Six people were killed and 30 others wounded early on Friday when two buses and three vehicles drowned in the water flooding a highway connecting the governorates of Qena and Sohag, some 500km south of Cairo, according to the health ministry.
Authorities closed off the road in both directions after many vehicles had been trapped by the waters, a provincial official told Ahram Arabic news website.
Twenty-six ambulances were rushed to the scene of the accident, Ahmed Al-Ansary, head of the ambulance authority, told Ahram Arabic news website.
Seven others were killed and 18 injured in the city of Ras Gharib, in the northern part of the Red Sea governorate, as a result of heavy rains hitting the area.
At least one person has been missing since Thursday, an Ahram Arabic reporter added.
Heavy rains flooded several Red Sea and Upper Egypt governorates on Wednesday and Thursday. The capital Cairo has been spared the unstable weather conditions.
