The scenes of violence has drawn widespread condemnation when Israeli police beat pallbearers at the funeral for slain Palestinian journalist Shireen Abu Akleh.
The US and EU have led an international outcry after Israeli police charged the funeral procession of Palestinian journalist Shireen Abu Akleh and beat pallbearers who almost dropped her coffin.
The United States said on Friday it was "deeply troubled" by the scenes, while the European Union said it was "appalled" by the "unnecessary force".
In a rare, unanimous statement, the UN Security Council condemned the killing and called for "an immediate, thorough, transparent, and impartial investigation," according to diplomats.
UN Secretary-General Antonio Guterres was also "deeply disturbed" by the violence, according to a spokesman.
Television footage showed the pallbearers struggling to stop Abu Akleh's casket from falling to the ground as baton-wielding police officers charged towards them, grabbing Palestinian flags from mourners.
The Jerusalem Red Crescent said 33 people were injured, of whom six were hospitalised. Israeli authorities said six arrests were made after mourners had thrown "rocks and glass bottles".
'EU appalled by the violence'
As Abu Akleh's body left St Joseph's hospital in Israeli-annexed east Jerusalem, Israeli police stormed mourners who had hoisted Palestinian flags.
Police said about "300 rioters" had arrived at the hospital for the procession and "prevented the family members from loading the coffin onto the hearse to travel to the cemetery — as had been planned and coordinated with the family in advance".
The police then intervened "to disperse the mob and prevent them from taking the coffin, so that the funeral could proceed as planned." Glass bottles and other objects were thrown at the police, it added in a statement.
The EU said it was "appalled by the violence in the St Joseph Hospital compound and the level of unnecessary force exercised by Israeli police throughout the funeral procession."
'Killed in cold blood'
Israel and Palestinie traded blame for the death of Abu Akleh on Wednesday who was shot in the head during the Israeli army raid on the Jenin refugee camp.
The Israeli army said an interim investigation could not determine who fired the fatal bullet, noting stray Palestinian gunfire or Israeli sniper fire aimed at militants were both possible causes.
But the Palestinian prosecutor's office in the West Bank city of Ramallah said later the initial results of an investigation showed "the only origin of the shooting was the Israeli occupation forces". Al Jazeera has said Israel killed her "deliberately" and "in cold blood".
