UAE President His Highness Sheikh Mohamed Bin Zayed Al Nahyan has directed the provision of $20 million in humanitarian aid to the Palestinian people.
The aid, which will be channelled through the United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA), comes as part of the UAE's policy to provide urgent relief and assistance to vulnerable populations and those in need around the world in times of crisis.
Israel's total siege of the Gaza Strip, depriving civilians of goods essential for survival, is banned under international law, the United Nations human rights chief said on Tuesday.
Volker Turk called for all sides instead to defuse the "explosive powder-keg situation", as Israel warned of a sustained war to destroy the Palestinian group Hamas.
"We know from bitter experience that vengeance is not the answer, and ultimately innocent civilians pay the price," Turk said.
Hamas, which abducted about 150 people in its surprise weekend assault on Israel, threatened to execute the hostages if Israeli air strikes continue "targeting" Gaza residents without warning.
The threat came after Israel on Monday imposed a total siege on the Gaza Strip, cutting off food, water and electricity supplies.
"The imposition of sieges that endanger the lives of civilians by depriving them of goods essential for their survival is prohibited under international humanitarian law," Turk said in a statement.
The siege risks seriously compounding the already dire human rights and humanitarian situation in Gaza, the statement said.
