Six Palestinians have been killed by the Israeli army in the West Bank in a new wave of violence between the two sides.
Five were killed after protesters started throwing stones at Israeli troops, while the sixth was shot after ramming his car into a military post and then trying to stab a soldier, officials said.
Most of the deaths occurred after live fire by troops, they added.
Separately, the Palestinian Ministry of Health said seven had been killed and more than 500 injured throughout the territory.
Dr Mustafa Barghouti, an independent Palestinian politician, told Sky News 60 similar protests were taking place across the West Bank on Friday.
Speaking in Ramallah, he described this week's fighting as a "really unprecedented uprising" and said those killed were "just participating in protest and demonstrations".
It comes after five days of airstrikes and rocket fire between Israel and Hamas that continued heavily through Friday.

Amid the widespread West Bank protests, the Israeli Defense Force (IDF) fired warning shots at a group of demonstrators who had crossed the border from Lebanon to take part in the rallies.
The army said that the group of youths damaged the border fence and set fire to the area before fleeing back to the Lebanese side.
One person was injured in the incident according to Al-Manar TV, which is run by Hezbollah, the Lebanese militant group.
Lebanon had fired three rockets towards Israel late on Thursday, in an apparent show of solidarity to the Palestinians in the occupied territories, but they landed in the Mediterranean Sea and caused no damage.
On Friday, a pre-dawn offensive saw Israeli forces use tanks, artillery units and 160 aircraft to unleash its heaviest attack on Gaza so far.
A military spokesman said it was focusing on underground tunnels, which they believe are used by Hamas militants.
Hamas and smaller Palestinian terror group Islamic Jihad, continued to launch rockets from the strip into Israel on Friday.
Dr Barghouti told Sky News correspondent Mark Stone in Ramallah that "Hamas and others are saying they are ready immediately for a ceasefire, but Israel is refusing".
In a video statement on Friday, Israeli Prime Minister Benjamin Netanyahu said: "I said we would extract a heavy price from Hamas.
"We are doing that, and we will continue to do that with heavy force."
Hamas military spokesman Abu Obeida said the group was not afraid of an Israeli ground invasion, which would be a chance "to increase our catch" of Israeli soldiers.
Despite Egyptian and other international attempts at mediation, fighting is also ongoing in 'mixed' Israeli towns where Arabs and Jews live side-by-side.
Israeli President Reuven Rivlin described the rioting as "senseless civil war".
