Footage shows protesters chanting 'F*** the Jews' outside Sydney Opera House

Footage circulating on social media shows protesters waving Palestinian flags and chanting “f* the Jews” outside the Sydney Opera House on Monday night.

A pro-Palestine rally was planned for Monday evening outside Sydney’s Town Hall. According to local media, protesters then marched to the opera house.

The state’s premier, Chris Minns, announced on Sunday that Sydney’s iconic landmark would be lit up with the colours of the Israeli flag.

Australian police said on Tuesday they were investigating the protest.

Around 1,000 pro-Palestinian supporters marched through downtown Sydney on Monday evening to the city's Opera House.

Israeli TV channels said the death toll from a Hamas attack over the weekend had climbed to 900 Israelis, with at least 2,600 injured, and dozens taken captive.

Among the Israeli dead were 260 mostly young people gunned down at a desert music festival, where some of the hostages were abducted.

Israeli Prime Minister Benjamin Netanyahu vowed revenge in a fiery speech accusing Iran-backed Hamas of executing tied-up children and other atrocities. "This vile enemy wanted war and it will get war," he said.

Gaza's Health Ministry said at least 687 Palestinians had been killed and 3,726 wounded in Israeli air strikes on the blockaded enclave since Saturday.

Apartment blocks, a mosque and hospitals were among the sites attacked, and the strikes destroyed some roads and houses, according to media reports and eyewitnesses.

Israel also bombed the headquarters of the private Palestinian Telecommunication Co., which could affect landline telephone, internet and mobile phone services.

The strikes continued into the night on Monday. The Israeli military said it hit targets in the Gaza Strip from the sea and air, including a weapons depot it said belonged to Islamic Jihad and Hamas targets along Gaza's coast line.
