Thirteen people were injured when a bus fell off a narrow bridge in the Nesigwe area of Nkayi, Matabeleland North.
The accident happened early Sunday as the bus, owned by Ntubeni Bus Services, made its way from Zhamba in Gokwe to Bulawayo.
Driver error is suspected after the bus overlapped the left side edge and fell into the rocky, dry Gwelo River bed, landing on its side.
Deputy Transport Minister Fortune Chasi said: "Sure, we do need to work on some bridges. However, what we urgently need to address is driver behaviour."
Locals complain that the bridge is too narrow and also curves at one end, posing a challenge to drivers. The bus, however, appeared to have fallen off in a straight stretch.
