JERUSALEM — The Israeli security cabinet convened for urgent discussions late Sunday, amid fears that a standoff over Israel’s placement of metal detectors at entrances to the sacred Aqsa Mosque compound could result in a long wave of violence.

After a weekend of bloodshed, Palestinian Muslims continued their protest by refusing to enter the compound.

Later, there were indications that the violence may have spread to Jordan, the custodian of the shrine and an important regional ally of Israel.

Jordan’s official news agency, Petra, and Jordan’s Public Security Directorate reported on Sunday night that two Jordanians had been killed and one Israeli had been wounded in a shooting inside the Israeli Embassy compound in Amman, the Jordanian capital. The agency, citing the Security Directorate, said the two Jordanians had entered the embassy’s compound to do carpentry work. There was no information from officials in Israel, where there was a news blackout on the report.
