Nearly 100 South African firefighters are battling a blaze on Cape Town's mountain range.

Thousands of hectares of vegetation have been reduced to ashes on Chapman's Peak, while several homes and a holiday lodge have been destroyed.

More than 50 people - residents of a retirement home - have been treated for smoke inhalation, officials say.

Four helicopters are on the scene, water-bombing the area.

The fire started on Sunday and was fanned by strong winds causing it to spread rapidly.

Roads around that area have been closed because of poor visibility.
