Jordan used tear gas to suppress protests against a curfew imposed to stem a severe outbreak of COVID-19, witnesses and residents said.
Police took action after hundreds of protesters in several cities including Amman demonstrated for a second day and defied a night curfew which was extended last week, they said.
Many of the protesters called on the government to resign and demanded an end to emergency laws in place since the outset of the pandemic, which civic groups say violate civil and political rights.
Others were angry after nine people, mostly COVID-19 patients, died on Saturday when medics in a government hospital allegedly ignored depleted oxygen supplies on respirators for at least two hours.
Authorities deployed several thousand anti-riot police to disperse protesters as dozens of activists were rounded up in several cities and towns, witnesses said.
Tear gas was used to disperse crowds in several cities including the teeming Jabal Nazal neighbourhood of the capital, a resident said.
The authorities blocked certain Facebook applications that allow live broadcasting from demonstrations, users and sources within the telecommunications sector told Reuters. The outage lasted several hours.
There was no immediate comment from the government.
The curfew has been extended several times since it was imposed a year ago, most recently on Saturday amid a surge in COVID-19 infections.
Jordan reported 9,417 new coronavirus infections in the past 24 hours, officials said on Monday, its highest one-day tally since the pandemic began. The country of 10 million people has recorded 5,428 deaths from the virus.
Jordan's King Abdullah said in comments broadcast on state media he understood that people were frustrated over worsening living conditions. Jordan last year suffered its worst recession in decades as a result of the pandemic.
But he warned his countrymen not to be swayed by dissidents, saying they sought "to sow internal strife".
Anger with the authorities over worsening living standards and corruption has in the past triggered major civil unrest in Jordan.
Many of the protesters were a mix of the country's traditional Herak opposition who demand radical political change and self-employed wage-earners hurt by the shutdowns.
