At least 38 activists were detained in Tel Aviv alone for “violating public order” and allegedly “attacking police officers”.

Multiple people were wounded in clashes, including Tel Aviv Mayor Ron Huldai, who received an injury to his hand, as protesters accused police of using excessive force.

Slammed by critics as a draconian crackdown on freedoms, the law prohibits Israelis from gathering more than one kilometer from home, to maintain “socially-distanced bubbles.”

The controversial law effectively put an end to massive anti-government marches and weekly rallies outside of prime minister Benjamin Netanyahu’s residence. However, the total number of people protesting in smaller groups in hundreds of places this Saturday could be even higher than before, according to some media estimates.

Israel has endured months of anti-government protests, primarily focusing on the alleged corruption of the prime minister. Netanyahu has been entangled in several criminal probes and protesters have called for his resignation.

The coronavirus crisis and its handling by the government have generated further dissatisfaction, which only deepened after the second nationwide lockdown went into effect on September 18 amid a surge in new infections.

“Down with feudalism, long live the people,” was one of the chants.

Protests have been building since mid-July to call for the removal of the government, a new constitution and elections. They have also broken a long-standing taboo by criticizing the monarchy of King Maha Vajiralongkorn.

Police said at least 5,000 people had gathered at the campus of Thammasat University, long seen as a hotbed of opposition to the military and royalist establishment, and scene of a massacre of protesters in 1976.

Under light rain, protesters spilled onto Sanam Luang, a public space opposite the Grand Palace where state ceremonies are traditionally held.

“Today the people will demand back their power,” Arnon Nampa, a human rights lawyer who has emerged as a leading figure in the protest movement, said on Twitter, Reuters reported.

Sept. 19 is the anniversary of the coup against the populist then-prime minister Thaksin Shinawatra in 2006. Among the protesters were many of his red shirt followers, veterans of clashes a decade ago with pro-establishment yellow shirts.

“I’m here to fight for the future of my children and grandchildren. I hope that by the time I die, they will become free,” said 68-year-old Tasawan Suebthai, a redshirt with amulets round her neck to ward off bullets.

So far the protests have been peaceful. The biggest to date drew more than 10,000 people last month, but organizers expect more this time.

Thai politics has for years been marked by challenges to the royalist and military establishment by politicians backed by poor urban and rural voters, and more recently by the student protesters.

The military, which proclaims itself the defender of the country’s core institutions, in particular the monarchy, has stepped in to overthrow civilian governments numerous times, most recently in 2014, citing the need to maintain stability.

Prayuth has said the government would allow protests as a form of free speech but that demands for reform of the monarchy were not acceptable.

“We are fighting to put the monarchy in the right place, not to abolish it,” one protest leader, Panupong “Mike” Jadnok, told the crowd.

A 20-year-old student, who gave her name only as Waan for fear of reprisals, said it was time to reform the monarchy. “It’s a problem that’s been swept under the rug for so long. This must end right here.”

Protesters demand the scrapping of a lese majeste law against criticism of the monarchy. They also seek to reduce the king’s constitutional powers and his control over the palace fortune and units of the army.

On Thursday, Prayuth warned the protesters against raising the risks of spreading the novel coronavirus and urged them to put the health crisis before politics.

Protesters jeered when a police officer told a group of them that they could only stay for an hour because of the risk of transmitting the virus. Police said they were deploying 10,000 officers on Saturday.
