Forty-two Zimbabwean and Malawian nationals have died after a bus taking them home overturned on a South African road, authorities have said.

The crash happened on Sunday night as the bus was moving through “a mountainous section” of the N1 highway in South Africa’s Limpopo province, local transport officials said.

“It [then] veered off the road along a steep mountain pass and plunged down an embankment,” they added.

South African President Cyril Ramaphosa mourned the high death toll, which includes seven children, and said this was not only a tragedy for the country but for “our sister states of Zimbabwe and Malawi” as well.
