Nurses in Eswatini are refusing to treat police officers as they accuse them of shooting colleagues during a pro-democracy rally on Wednesday.
Protests in Africa’s last absolute monarchy, formerly known as Swaziland, have swept the country since June.
Some internet services, such as Facebook, were temporarily shut down this week in response to the unrest.
The government, which denies that security forces used live ammunition, has now banned all demonstrations.
“We have no reports of nurses being shot,” a government spokesperson told BBC Focus on Africa.
“Police are on the streets to maintain law and order, there is no willy-nilly shooting.”
He added that Eswatini was a country founded on peace and dialogue.
On Friday nurses were protesting at three hospitals, reports say.
