António Guterres was speaking to journalists at UN Headquarters in New York following  meeting with senior UN leaders on what he called the "unprecedented developments" in Israel and the Occupied Palestinian Territory.

“Let me begin by repeating my utter condemnation of the abhorrent attacks by Hamas and others against Israeli towns and villages in the Gaza periphery, which have left over 800 Israelis dead and more than 2,500 injured,” he said.

"Sadly, these numbers are expected to rise as the attacks are ongoing and many remain unaccounted for,” he added.

He further noted that over 100 Israelis -  civilians and military, including women, children and the elderly - have been reported captured by armed groups. Some are being held hostage inside Israel and many others have been taken inside the Gaza Strip.

Meanwhile, Hamas and Palestinian Islamic Jihad have launched thousands of indiscriminate rockets that have reached central Israel, including Tel Aviv and Jerusalem.

No justification for terror

“I recognize the legitimate grievances of the Palestinian people.  But nothing can justify these acts of terror and the killing, maiming and abduction of civilians,” he said. “I reiterate my call to immediately cease these attacks and release all hostages.”

In the face of these unprecedented attacks, Israeli airstrikes have pounded Gaza, he continued.
 
“I am deeply alarmed by reports of over 500 Palestinians -- including women and children -- killed in Gaza and over 3,000 injured.  Unfortunately, these numbers are rising by the minute as Israeli operations continue,” he said.

Respect international humanitarian law

“While I recognize Israel’s legitimate security concerns, I also remind Israel that military operations must be conducted in strict accordance with international humanitarian law.”

The Secretary-General stressed that civilians must be respected and protected at all times, and that civilian infrastructure must never be a target.

He pointed to reports that  Israeli missiles had struck health facilities inside Gaza as well as multi-storied residential towers and a mosque.  Two schools run by UNRWA, the UN agency that assists Palestinian refugees, that were sheltering displaced families in Gaza were also hit.
 
Overall, some 137,000 people are currently sheltering in UNRWA facilities, he continued, adding that numbers are increasing. 

Humanitarian concerns

Mr. Guterres was deeply distressed by the announcement that Israel will initiate a complete siege of the Gaza Strip.

“The humanitarian situation in Gaza was extremely dire before these hostilities; now it will only deteriorate exponentially,” he said.

“I urge all sides and the relevant parties to allow United Nations access to deliver urgent humanitarian assistance to Palestinian civilians trapped and helpless in the Gaza Strip. I appeal to the international community to mobilize immediate humanitarian support for this effort.”

End the violence

The Secretary-General said this most recent violence “does not come in a vacuum” but “grows out of a long-standing conflict, with a 56-year long occupation and no political end in sight.”

He appealed for an end to "the vicious cycle of bloodshed, hatred and polarization."

“Israel must see its legitimate needs for security materialized – and Palestinians must see a clear perspective for the establishment of their own state realized,” he said.

“Only a negotiated peace that fulfills the legitimate national aspirations of Palestinians and Israelis, together with their security alike – the long-held vision of a two-State solution, in line with United Nations resolutions, international law and previous agreements – can bring long-term stability to the people of this land and the wider Middle East region.”
