An order allowing the use of lethal fire against thousands of young, unarmed protesters in Nepal was issued by the country's former police chief, a BBC investigation reveals.
Among the 19 people killed in the capital, Kathmandu, on 8 September last year was a teenager in school uniform, who had been walking away from the crowd when he was shot in the back of the head. Dozens more were injured.
The events at the so-called Gen Z demonstrations - which had followed weeks of simmering anger about political corruption - sparked further protests leading to the resignation of Nepal's prime minister and the collapse of its government a day later.
The BBC World Service team has seen an internal police document detailing events on 8 September. It reveals someone using the call sign "Peter 1" told his officers to "deploy necessary force" 10 minutes after a curfew had come into effect, and after repeated requests by officers on the ground to use lethal force.
Peter 1 was the call sign used by Nepal's former police inspector general, Chandra Kuber Khapung, sources have told BBC Eye Investigations.
