Israeli forces in the occupied West Bank have clashed with Palestinians protesting against the US declaration of Jerusalem as Israel's capital.

Demonstrators in Bethlehem threw stones and troops fired tear gas. There are unconfirmed reports of injuries.

Tensions are high in the West Bank and Jerusalem amid calls for protests from Palestinian leaders.

Donald Trump's announcement was hailed by Israel but condemned across the Arab and Islamic world.

Western allies of the US have also disavowed the move, which reversed decades of US policy of neutrality towards Jerusalem's status.

• Anger in the West Bank and delight in West Jerusalem

Israel has always regarded Jerusalem as its capital, while the Palestinians claim East Jerusalem - occupied by Israel in the 1967 war - as the capital of a future Palestinian state.

In recognising Jerusalem as Israel's capital, the US became the first country to do so since the foundation of the state in 1948.

Where has there been violence?

Television pictures from Bethlehem show hundreds of chanting protesters facing off with Israeli troops along a main street.

Water cannon is being used to try to disperse the crowds, while clouds of tear gas and thick, black smoke from a burning tyres fill the air.

Extra battalions have been deployed to the West Bank, after clashes there, as well as in part of East Jerusalem and on the Gaza-Israel border on Thursday, left dozens of Palestinians wounded.

Hundreds of additional police are also on duty in and around the Old City of Jerusalem. Demonstrations are being held outside the Old City walls after thousands of worshippers left the al-Aqsa Mosque compound where they held Friday prayers.

The Old City, containing contentious holy sites, is historically a flashpoint for violence.

The Fatah faction of Palestinian President Mahmoud Abbas called for Palestinians to take to the streets, while the Gaza-based militant Islamist group Hamas has called for a "day of rage" and a third intifada, or uprising, against Israel.

• Five key takeaways from speech

Israeli forces struck "two military posts" in Gaza on Thursday, the army said, after three rockets were fired at Israel from inside the Palestinian enclave. There were no reports of injuries.

Elsewhere, demonstrations against Donald Trump's announcement have spread.

How has the international community reacted?

There has been widespread denunciation of Mr Trump's move, especially in the Muslim world.

America's closest Arab allies, Saudi Arabia, Egypt and Jordan, have expressed their opposition, while Egypt, Bolivia, France, Italy, Senegal, Sweden, the UK and Uruguay have called an emergency meeting of the UN Security Council on Friday to discuss the step.
