More than 4000 Sydney protesters joined hundreds of thousands around the world on Sunday to demand an end to Israeli military strikes on Gaza.

Best friends Batoul Taha, 25, and Kiltom Al-Tobi, 25, held placards showing images of Palestinian children injured or killed in air strikes. They said they travelled an hour from the western suburbs to attend the rally.

“We are just over it. We are over people being killed in Palestine, especially the children,” said Taha, who lives in Merrylands.
