Durban - A man killed his wife before he committed suicide by shooting himself in the head in Durban on Friday morning, KwaZulu-Natal police said.

The couple apparently had an argument in their car and the man shot his wife, who was driving, police spokesman Captain Thulani Zwane said.

The woman died on the scene and the man was declared dead on arrival at a hospital. Police recovered the man's firearm and a murder docket was opened.

Paramedics found the car wedged against a tree, at the intersection of Essex Street and Durham Road around 8am, Netcare 911 spokesman Chris Botha said. The two were in their 50s.
