K.P. Sharma Oli has resigned after violent anti-corruption protests shook his country over the weekend

Nepal Prime Minister K.P. Sharma Oli resigned on Tuesday, his aide Prakash Silwal said, as anti-corruption demonstrators defied an indefinite curfew and clashed with police, a day after 19 people died in violent protests triggered by a social media ban.

“The PM has quit,” Silwal told Reuters, a move that plunges the country into fresh political uncertainty.

But anger against the government showed no signs of abating, as protesters gathered in front of parliament and other places in the capital Kathmandu, in defiance of an indefinite curfew imposed by authorities.

The protesters set fire to tyres on some roads, threw stones at police personnel in riot gear and chased them through narrow streets, while some looked on and shot videos of the clashes on their mobile phones as thick black smoke rose to the sky.
