In the past, Israel was willing to pay a high price to protect the relationship, including releasing an Islamic militant leader from prison in a deal with Jordan.
Palestinians walk next to the entrance of the compound known to Muslims as Noble Sanctuary and to Jews as Temple Mount at morning after Israel removed the new security measures there, in Jerusalem's Old City July 25, 2017.
One person set off a firework, prompting Israeli police to raid and disperse them using sound grenades. The incident came at the worst possible time for Israel, complicating efforts to find a way out of the standoff over the metal detectors at the Jerusalem site.
Details of the advanced technologies envisaged were not immediately clear.
Muslim leaders had demanded that security arrangements go back to what they were before the metal detectors were erected. "We can also not accept Jews going to synagogues and temples being treated as terrorists", he said.
Israel installed metal detectors at entrances to the compound after two police officers on guard there were fatally shot on July 14.
Several hundred worshippers prayed outside the gates in the streets in the summer heat, as they have done since the metal detectors were installed more than a week ago.
The installation of the detectors led to widespread anger among Muslims, who boycotted praying at the site in protest, and sparked a series of violent clashes with Israeli security forces, during which five Palestinians were killed. The Palestinian president had announced last week that he was suspending all ties with Israel, including security co-ordination between his forces and Israeli troops in the West Bank, until the metal detectors are removed.
The knife attack was condemned by Israeli Prime Minister Benjamin Netanyahu.
Jason Greenblatt, a top aide to U.S. President Donald Trump, met with Netanyahu along with U.S. envoy to Israel David Friedman on July 24, an Israeli official told the AFP news agency.
On Monday the UN's Middle East envoy warned of "potential catastrophic costs" even beyond the region if the issue was not resolved by Friday, when Muslims traditionally flock to the site for prayers.
"We reject the metal detectors". A second Jordanian who died was inadvertently killed by the gunfire, Israel said.
Observers said Israel would not risk irritating the whole Arab world as it had enjoyed a relatively peaceful environment after years of strained relations with regional countries that had become involved in the Syrian war.
"What we want and what we demand is for everything to return how it was before July 14", said Mohammed Hijazi, who came from Acre in northern Israel to join the protests. The king called on Mr Netanyahu to remove the metal detectors.
Friday's main weekly Muslim prayers - which typically draw thousands to Al-Aqsa - had brought the situation to a boil.
The violence left four Palestinians dead in East Jerusalem and the occupied West Bank, while three Israeli civilians were stabbed to death by a Palestinian who had said he was avenging Israeli measures at the holy site. The security move touched off the bloodiest clashes between Israelis and Palestinians for years. It has been a flashpoint site of the Israeli-Palestinian conflict in the past decades since the 1967 Israeli occupation of East Jerusalem.
It lies in east Jerusalem, seized by Israel in the Six- Day War of 1967 and later annexed in a move never recognised by the global community.
