The UN commission of inquiry on Tuesday announced that it has "clear evidence" that war crimes may have been committed in latest violence in Israel and Gaza.
"There is already clear evidence that war crimes may have been committed in the latest explosion of violence in Israel and Gaza, and all those who have violated international law and targeted civilians must be held accountable for their crimes," said the UN Independent International Commission of Inquiry on the Occupied Palestinian Territory, including East Jerusalem and Israel.
The commission said that it has been collecting and preserving evidence of alleged war crimes committed by all sides since Saturday.
"Reports that armed groups from Gaza have gunned down hundreds of unarmed civilians are abhorrent and cannot be tolerated. Taking civilian hostages and using civilians as human shields are war crimes," the commission said.
It added: "The Commission is gravely concerned with Israel's latest attack on Gaza and Israel's announcement of a complete siege on Gaza involving the withholding of water, food, electricity and fuel which will undoubtfully cost civilian lives and constitutes collective punishment."
The commission called for the "unconditional and safe" release of all individuals who have been taken hostage by the Palestinian armed groups.
It emphasized that the only path toward ending violence and achieving sustainable peace is "through addressing the root causes of the conflict including through ending the illegal occupation of Palestinian territory and recognising the right of the Palestinian people to self-determination."
The Gaza-based resistance group Hamas launched Operation Al-Aqsa Flood against Israel early Saturday, firing a barrage of rockets. It said the surprise attack was in response to the storming of Al-Aqsa Mosque in occupied East Jerusalem and increased settler violence.
In retaliation, the Israeli army launched Operation Swords of Iron against Hamas in the Gaza Strip.
At least 800 Israelis have been killed and over 2,300 others wounded in the fighting, according to the Israeli Health Ministry.
The Palestinian Health Ministry said that 760 Palestinians have been killed and more than 4,000 wounded.
