Kenya is bringing in a ban on people using plastic bags to dispose of their organic waste, burnishing the country's status as a global leader in the fight against plastic pollution.

It comes seven years after the East African nation banned single-use plastic bags.

The country's environmental agency says residents and local authorities now have three months to prepare for the changes before they will be enforced.

News of the changes were widely circulated to the public on Monday but, according to the statement sent out, they had first been issued on 8 April.
