Police in the Australian city of Sydney have used pepper spray against pro-Palestine protesters who have rallied against a visit by Israeli President Isaac Herzog.

A journalist with the AFP news agency witnessed police arresting at least 15 demonstrators during the confrontation on Monday. Media members covering the event were also affected by pepper spray.

Thousands of demonstrators gathered in Sydney’s business district with more protests planned across the country on Monday night.

In Melbourne’s city centre, simultaneous protests took place with participants demanding an end to Israel’s occupation of Palestinian territory. About 5,000 protesters gathered outside downtown Flinders Street Railway Station before marching several blocks to the State Library, blocking evening peak-hour traffic, according to police.

The protests continued despite Palestine Action Group organisers losing a court challenge of a police order barring them from marching from the Town Hall in Sydney to the New South Wales Parliament.

A 20-year-old woman was arrested after allegedly burning two flags and causing fire damage to a tram stop. Police released her but said she was expected to face wilful damage charges.

Activists said Herzog, whom a United Nations commission of inquiry has found to be responsible for inciting genocide against Palestinians, should not be immune to protests.

“President Herzog has unleashed immense suffering on Palestinians in Gaza for over two years – brazenly and with total impunity,” Amnesty International’s Australia chapter said. “Welcoming President Herzog as an official guest undermines Australia’s commitment to accountability and justice. We cannot remain silent.”

Herzog characterised the protests as mostly attempts to “undermine and delegitimise” Israel’s right to exist.

Earlier, Prime Minister Anthony Albanese had called for respectful behaviour during Herzog’s visit, noting he would join the president to meet families of the victims of the December Bondi Beach mass shooting.

New South Wales authorities implemented recently expanded police powers under new protest management legislation. Protesters’ legal challenge to these measures was rejected by the state’s Supreme Court shortly before the demonstrations began.

Herzog had earlier laid a wreath in the rain at Bondi Pavilion to honour victims of the attack that killed 15 people during a Hanukkah celebration.

The Israeli president began his four-day Australian visit there. He also met with survivors and victims’ families.

“This was also an attack ‌on all Australians,” Herzog said at the site. “They attacked the values that our democracies treasure, the sanctity of human life, the freedom of religion, tolerance, dignity and respect.”

“I’m here to express solidarity, friendship and love,” he added.
