Indonesia haze work 'will take three years'

Efforts to tackle the forest fires which pollute air across South East Asia every year will take at least three years to complete, Indonesia's president has said.

The fires are started by farmers and landowners clearing land for crops. The haze they generate is an increasing source of tension between Indonesia and its neighbours.

In an exclusive BBC interview, Joko Widodo said it was not an easy problem to solve.
