In the hospital National Trauma Center in the Nepalese capital, nearly 60 injured are being treated at the moment.
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.
Outside several hospitals, anxious relatives are now waiting for news. In other places, the protests continue.
The demonstrators' anger has been 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.
It seems to have been the drop that made many of the tens of thousands of activists take to the streets.
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.
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 to reach the parliament and clashed with riot police, who in turn opened fire.
16 people have been killed and nearly 90 people injured, according to police spokesperson Shekhar Khanal.
