WINDHOEK, March 20 (Xinhua) -- Five people were killed after a head-on collision between a sedan and a pick-up truck on Namibia's main B1 highway on Thursday evening, local media reported Friday.

All victims were passengers in the sedan and the driver of the pick-up truck suffered serious injuries, the Namibia Broadcasting Corporation (NBC) reported.

Both vehicles burst into flames after the crash in the Otjozondjupa Region of central Namibia.
