Israeli police charged at and brutally assaulted Ìýcarrying Abu Akleh's casket on Friday as they carried her body from the hospital in occupied East JerusalemÌýwhere it was being kept, in harrowing scenes broadcast live.

Officers fired tear gas and stun grenades,Ìýkicked, and beat Palestinians with batons, as they attempted to snatch national flags away. The assault almost caused the coffin to be dropped to the floor.

"We are talking about a hospital. We are not talking about a battlefield," said an Al Jazeera journalist watching events unfold, adding that there were injuries.

Reacting to the attack, Al Jazeera senior political analyst Marwan Bishara said: "This is unbelievable, unbelievable.

"Oh my God. Such disrespect for the dead and for those who are mourning the dead.

"Please tell me – and maybe our viewers around the world will tell us – how are these people a threat to Israel?"

"The Israeli army is asking people if they are Christian or Muslim. If you’re Muslim you weren’t allowed in." -

Police claimedÌý"stones began to be thrown at officers" before they were "forced to use riot dispersal means" – but the footage broadcast by Al JazeeraÌýshowed peaceful mourners, including coffin-bearers, being attacked without any signs of provocation.

An Israeli officer outside the hospital threatened Palestinians on a loudspeaker, a video published by the police showed.

Those gathered were told: "If you don’t stop these chants and [Palestinian] nationalistic songs we will have to disperse you using force and we won't let the funeral take place."

The Palestinian flag is banned by Israel, and its forces commonly use violence against people carrying itÌýin Jerusalem during big public events.

The Palestinian Red Crescent Society said it dealt with dozens of injuries, °®Âþµº's sister site, Al-Araby Al-Jadeed, reported.

Abu Akleh's body was then placed in a hearse – which Israeli forces attacked, preventing anyone from escorting the car from the hospital to the church.

Israeli securityÌýwould notÌýallow her body to be carried out of the hospital on foot and refused to letÌýher brother, Anton Abu Akleh,Ìýsit in the hearse.

They closedÌýthe hospital gates, sprayed skunk water,Ìýand arrested mourners.

Anton described Shireen as "the sister of all Palestinians", speaking with AFP.

Another mourner, Hadil Hamdan, said: "Her voice entered every home, and her loss is a wound in our hearts."

Before the funeral, Israel had demanded of Abu Akleh's family that there be no chants or Palestinian flags raised during the processionÌýand that a hearse be used to transport her body -Ìýbut mourners refused to comply.

Near the Catholic church where her funeral mass was said, police again assaulted participants, and a Palestinian flag was pulled off her casket.

After mass, Israel shut the Old City's Hebron Gate, preventing Palestinians from reaching the Mount Zion Cemetery where Shireen was laid to rest next to her parents.

A church source said 13 Jerusalem churches from different Christian denominations rang their bells in mourning.
