Israel says it has targeted sites in Gaza belonging to militant group Hamas in retaliation for rocket strikes.
Israel’s military said it hit weapons sites early on Saturday. Two people were killed, a Gaza hospital said, bringing the deaths in Israeli strikes and gunfire over the past day to four.
Israeli-Palestinian tensions have risen since President Donald Trump recognised Jerusalem as Israel’s capital.
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.
Earlier on Friday, Fathi Hammad, a senior Hamas leader, said anyone seeking to move their embassy to Jerusalem was “an enemy of the Palestinians”.
Speaking before the United Nations on Friday, US ambassador Nikki Haley said the US “recognises the obvious; that Jerusalem is the capital of Israel”.
She said the US continued to be “committed to achieving a lasting peace agreement”, and accused the UN of bias, saying it “has outrageously been one of the world’s foremost centres of hostility towards Israel”.
“Israel will never be, and never should be, bullied into an agreement by the United Nations or by any collection of countries that have proven their disregard for Israel’s security,” Mrs Haley said.
Israel had deployed extra battalions to the West Bank in anticipation of violence after Palestinian leaders called for protests after Friday prayers.
At least 217 Palestinians were wounded in confrontations in the West Bank and East Jerusalem, Palestinian medics said.
There were protests held elsewhere on Friday against Mr Trump’s announcement.
Thousands of pro-Palestinian protesters held demonstrations in Jordan, Egypt, Iraq, Turkey, Tunisia and Iran.
Further afield, protesters rallied in Malaysia, Bangladesh, Pakistan, Afghanistan, Indian-administered Kashmir and Indonesia, the world’s largest Muslim-majority country.
