Thousands of people packed Jerusalem's Old City on Friday for the burial of veteran Al Jazeera reporter Shireen Abu Akleh, after Israeli police stormed the funeral procession.
Television footage showed pallbearers struggling to stop Abu Akleh's coffin from falling to the ground as baton-wielding police officers charged toward them, grabbing Palestinian flags from mourners.
Washington said it was "deeply troubled" by the scenes, while the European Union said it was "appalled" by the "unnecessary force."
According to the Jerusalem Red Crescent, 33 people were injured during the procession, of whom six were hospitalized.
Israeli police said they made six arrests. A government official said mourners had thrown "rocks and glass bottles".
In a fresh shootout in the occupied West Bank, an Israeli commando was killed near the flashpoint city of Jenin. The Islamic Jihad group said its fighters were responsible.
Abu Akleh's death during an Israeli raid in Jenin on Wednesday has Israel and Palestine exchanging blame.
The Israeli army said an interim investigation could not determine who fired the fatal bullet, noting that stray Palestinian gunfire or Israeli sniper fire aimed at militants were both possible causes.
Al Jazeera has said Israel killed her "deliberately" and "in cold blood".
In a rare, unanimous statement, the UN Security Council on Friday condemned the killing and called for "an immediate, thorough, transparent, and impartial investigation," according to diplomats, who noted negotiations over the wording were particularly contentious.
Abu Akleh, a Christian and a Palestinian American, was a star reporter and her funeral drew massive crowds.
As her body left St Joseph's hospital in Israeli-annexed east Jerusalem, Israeli police stormed mourners who had hoisted Palestinian flags.
The Jewish state forbids public displays of Palestinian flags and routinely intervenes against those who parade them at demonstrations or other gatherings.
Police said they had warned the crowd to stop "nationalistic" songs and were forced to act as "violent rioters (were) trying to disrupt the proper course of the funeral".
But prominent Palestinian figure Hanan Ashrawi said the police charge on pallbearers showed Israel's "inhumanity".
The United States was "deeply troubled to see the images of Israeli police intruding into her funeral procession today," Secretary of State Antony Blinken said in a statement.
"Every family deserves to be able to lay their loved ones to rest in a dignified and unimpeded manner."
The EU tweeted that 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."
US President Joe Biden discussed ways to address the rising violence in White House talks with King Abdullah II of Jordan.
"The leaders... discussed urgent mechanisms to stem violence, calm rhetoric, and reduce tensions," the White House said in a statement.
The French consulate general said "police violence" at the hospital had been "deeply shocking".
And UN Secretary-General Antonio Guterres was "deeply disturbed" by the violence, according to a spokesman.
Thousands of Palestinian mourners attempted to follow the coffin towards the cemetery just outside the walled Old City.
Police briefly attempted to prevent them but ultimately relented, allowing thousands to stream towards the graveside, and did not intervene as Palestinian flags were waved, AFP reporters said.
'Sister of all Palestinians'
In a sign of Abu Akleh's prominence, she was given what was described as a full state memorial service on Thursday at Palestinian president Mahmud Abbas's compound in Ramallah before her body was transferred to Jerusalem.
"Her loss is a wound in our hearts," said mourner Hadil Hamdan.
The United States, European Union and United Nations have backed calls for a full investigation into Abu Akleh's killing.
Israel has publicly called for a joint probe, which the Palestinian Authority has rejected.
Grief over Abu Akleh's killing spilt beyond the Palestinian territories, with protests erupting in Turkey, Sudan and elsewhere.
She "was the sister of all Palestinians," her brother Antoun Abu Akleh told AFP.
Fresh violence erupted in the West Bank, including a raid and clashes around Jenin refugee camp.
The Israeli officer killed was identified as Noam Raz, a 47-year-old father of six. Police said he was wounded "during a shootout with armed terrorists," and later died.
The Palestinian health ministry said 13 Palestinians were wounded in the clashes, one of them seriously.
An AFP photographer said Israeli forces had surrounded the home of a suspect, besieging two men inside and firing anti-tank grenades at the house in an effort to flush them out.
Tensions were already running high after a wave of anti-Israeli attacks that have killed at least 18 people since March 22, including an Arab-Israeli police officer and two Ukrainians.
A total of 31 Palestinians and three Israeli Arabs have died during the same period, according to an AFP tally, among them perpetrators of attacks and those killed by Israeli security forces in West Bank operations.
