Nepal's prime minister KP Sharma Oli has resigned after violent anti-corruption protests.
"The PM has quit," his aide Prakash Silwal told Reuters news agency on Tuesday.
In his resignation letter, sent to Nepal's President Ram Chandra Paudel, Mr Oli said he is leaving with immediate effect "in order to take further steps towards a political solution and resolution of the problems [...] taking into account the extraordinary situation currently prevailing in the country."
The president has now begun the process to install a new PM, his aide said.
Mr Oli's exit comes as demonstrators defied an indefinite curfew, clashed with police and set politicians' homes on fire, a day after 19 people died in violent protests triggered by a social media ban.
