The UN Office on Drugs and Crime said the area used to farm the poppy plant, the source of opium, increased by 10% to 201,000 hectares. Afghanistan is the world's largest producer of the substance, which is the main ingredient in heroin.

BBC South Asia correspondent Justin Rowlatt visited poppy farms, where one farmer told him the local government knew about his crop, but "they also know it is the only way anyone can make decent money."
The famed American anti-war activist Tom Hayden has died in his home in Santa Monica, California, after a lengthy illness. He was 76.
