Iran’s foreign minister declared on Tuesday that ‘time is OVER’ for Israel, as Joe Biden arrived in Tel Aviv to try and calm a rapidly-spiraling situation, with anti-Israel protests flaring up across the region.

An air strike on a Gaza hospital on Tuesday evening, killing at least 500 people according to Palestinian authorities, enraged people around the world. Israel and Palestinians both blame each other for the atrocity.

Demonstrators in Beirut briefly set the U.S. embassy on fire in anger at the killings, and in Amman dozens of protesters attempted to storm the Israeli embassy.

Hossein Amir-Abdollahian, Iran’s foreign minister, arrived in Saudi Arabia on Tuesday after the hospital bombing – a remarkable show of unity between two former sworn enemies.

Saudi Arabia and Iran in March agreed a Chinese-mediated détente and have moved toward reopening diplomatic missions in each other’s countries: Amir-Abdollahian visited Saudi Arabia’s crown prince, Mohammed bin Salman, in August.

On Tuesday, Amir-Abdollahian, in Saudi for a meeting of the Organization of Islamic Cooperation, issued a stark threat to Israel, blaming them for the hospital bombing.

‘After the terrible crime of the Zionist regime in the bombing and massacre of more than a thousand innocent women and children in the hospital, the time has come for the global unity of humanity against this fake regime more hated than ISIS and its killing machine,’ he tweeted.

‘Time is OVER.’

Iran’s embassy in Syria also tweeted, in Hebrew and Arabic: ‘Time is up.’

Backing the Palestinian cause has been a pillar of the Islamic Republic since the 1979 revolution and a way the Shi’ite-dominated country has fashioned itself as a leader of the Muslim world.

Tehran says it gives moral and financial support to Hamas, which controls the Gaza Strip, but Western intelligence agencies do not believe that Tehran orchestrated the October 7 attack.

Iran immediately blamed Israel for the Gaza hospital attack, with Nasser Kan’ani, a spokesman for the foreign ministry, calling it a ‘savage war crime’ and an instance of ‘genocide.’

Kan’ani accused Israel of carrying out a ‘bestial and appalling crime,’ adding, according to state-run Press TV: ‘The Zionist regime once again showed its ferocious and vicious nature to the entire people of the world.’
