Two Jordanians have been killed and an Israeli wounded in an incident next to Israel's embassy in Amman.
Israel's the foreign ministry said a Jordanian attacked a security guard with a screwdriver in a residential building used by the embassy.
He was one of two men delivering furniture to the building, it said in a statement.
One of the workers and the building's landlord were killed and the security guard was injured, it added.
It did not confirm earlier reports of shooting but said the guard had "acted in self-defence".
The incident came at a time of heightened tension in the region over a Jerusalem holy site.
Details of the incident in the Jordanian capital remain unclear. Israeli authorities imposed reporting restrictions in the immediate aftermath.
The building has been sealed off and staff evacuated.
The heavily protected Israeli embassy is located in the Rabiyeh neighbourhood, an affluent part of the capital city.
According to the Vienna Convention, the Israeli foreign ministry said, the security man has immunity from investigation and arrest.
Holy site row
On Friday, thousands of Jordanians protested in Amman against Israel over the installation of metal detectors at a site sacred to both Muslims and Jews in East Jerusalem.
Jordan, which occupied East Jerusalem from 1949 to 1967, is the custodian of the site, which is known to Muslims as Haram al-Sharif and Jews as the Temple Mount.
Tensions between Israelis and Palestinians over the site have surged in recent days in response to the metal detectors, which were put in place following the killing of two Israeli policemen.
Security cameras have now also been installed at a gateway leading to the site.
