The dead man has been named as Eliyahu David Kay, a recent immigrant from South Africa who worked as a guide on the Western Wall. The authorities corrected the age of the victim that they had previously reported.
Four other people, including a man whose condition was described as serious, were injured in the incident, which occurred on Sunday morning near the Chain Gate entrance to the al Aqsa Mosque complex, also known as the Mount of Temple.
The assailant, who used an improvised automatic weapon commonly known as a Carlo, police say, was shot and killed by police officers at the scene.
Israel’s public security minister, Omar Bar Lev, said the gunman was from the Shuafat neighborhood in east Jerusalem and a member of the Hamas political wing.
Hamas issued a statement identifying the attacker as Fadi Abu Shkaydam, calling him a heroic martyr and describing him as a local leader of the movement.
He said the attack was “a response to attempts to desecrate the Al Aqsa mosque.”
Israeli Prime Minister Naftali Bennett told government ministers that he was praying for the recovery of the wounded and had instructed the security forces to prepare for possible “copycat attacks.”
“We need to be more vigilant and prevent future attacks,” he said at the beginning of the weekly Cabinet meeting.
In a separate event on Sunday, police now say they are treating a stabbing incident in the city of Jaffa as possible terrorism.
A 67-year-old man was slightly injured, police said, after being stabbed by an unknown person who later escaped.
“The findings of the initial investigation reinforce suspicions that it was carried out for nationalistic reasons,” a later police report said.
Four days ago, a 16-year-old Palestinian was shot and killed after carrying out a stabbing attack on two Israeli border policemen in the Old City, police said.
