The security guard who killed his Jordanian assailant and a bystander after being stabbed in the chest said “a weight has been lifted from my heart” after returning to Israel.

The guard, identified as Ziv, met Tuesday morning with Israeli Prime Minister Benjamin Netanyahu and Israeli Ambassador to Jordan Einat Shlain.

“Thank you from my heart. I am happy to be here. Einat and I felt that people were standing behind us and were making every effort, we felt this and I am glad that we are here,” he told Netanyahu.

The employees of Israel’s diplomatic mission in Amman, Jordan, returned to Israel late Monday night through the Allenby Bridge border crossing.

In the attack Sunday, the assailant entered a residential building occupied by the embassy to install furniture and stabbed the Israeli guard with a screwdriver. The guard shot and killed his attacker, a 17-year-old Jordanian. The building’s owner, who was standing nearby, was killed after being hit by a stray bullet.

Late Monday, Jordan’s Public Security Directorate announced that its investigation determined that the assailant had attacked the Israeli guard, though it claimed there had been argument first between the teen and the guard over a delay in delivering the furniture.

The father of the slain teen said his son was not a member of any political group. He also publicly asserted that he had sold the furniture to a Jordanian national in order to distance himself from charges that he was “normalising ties” with Israel, The Jordan Times reported.

Jordanian police had demanded to question the guard, while relatives of the stabber called for the death penalty. The embassy refused to turn the guard over to the Jordanians for questioning, saying he had immunity.
