In the hospital National Trauma Center in the Nepalese capital, about 60 injured were being treated after Monday's clashes.
For many of them, the condition is serious. They appear to have been shot in the head and chest, says doctor Badri Risal to AP.
On Monday evening, the death toll had risen to at least 19 people, according to BBC, while official figures state that 17 people have been killed.
Blocking platforms
The demonstrators' anger was triggered by the government's decision to block 26 popular social media platforms, including Facebook, X and Youtube, since Friday.
Formally, it is stated that the companies behind the platforms have not registered and opened up for review by Nepalese authorities. The decision sparked strong protests.
We were triggered by the social media ban, but it's not the only reason we've gathered, says 24-year-old student Yujan Rajbhandari to AFP.
"See change"
We want to see change. We are protesting against the corruption that has been institutionalized in Nepal.
The flag-waving demonstrators broke through barbed wire fences to reach the parliament and clashed with riot police, who in turn opened fire.
The UN Office for Human Rights urges Nepal to conduct a thorough investigation into the incident.
"We are outraged that demonstrators have been killed or injured in Nepal today and call for an immediate and transparent investigation", says the spokesperson for the UN agency, Ravina Shamdasani, in a statement.
