Hundreds of Palestinian protesters are clashing with Israeli security forces in the West Bank cities of Hebron, Bethlehem and Ramallah.
The clashes began after Friday midday prayers in a show of rage over US President Donald Trump's decision to recognise Jerusalem as Israel's capital.
Protesters threw stones at Israeli troops who responded with tear gas and rubber bullets.
In Gaza, thousands took to the streets and marched on Friday to denounce Mr Trump's proclamation.
