TEL AVIV – A Palestinian teenager killed a 45-year-old Israeli-American man in the West Bank on Sunday, after US and Israeli officials.
The man, Ari Fuld, was a far-right pro-Israeli activist who had supporters in social media. He was killed in a mall near the intersection of Gush Etzion, which had similar incidents in recent years. The intersection and shopping center are frequented by both Israelis and Palestinians.
The Israeli military described the stabbing – the second such incident this summer – as an act of terror. No group took responsibility for the attack, and there was no indication that it was Mr. Fuld's pro-Israeli postings.
The attack takes place in the midst of heightened tensions between Israelis and Palestinians. Thousands of Palestinians in Gaza have demonstrated on the border with Israel to demand the right to return each week, in protests that have often been violent. Israeli forces fired fire, killing more than 150 Palestinians since March.
Mr. Fuld lived with his family in Efrat, a settlement in the West Bank, and was married to four children. He was also a reserve member of the Israeli military.
Videos of the scene, which were spread on social media, show that Mr. Fuld chased his attacker and shot him before he collapsed.
An Israeli police spokesman identified the attacker as Khalil Jabarin, 17, of Yatta, a Palestinian town south of Hebron. He was injured and evacuated to a hospital in Jerusalem.
According to the Israeli Foreign Ministry, more than 60 people have died in Palestinian attacks since September 2015, including stabbings, shootings and autos. This count includes two visiting Americans and one British student. In July, a 31-year-old Israeli man was stabbed and killed at his home by a Palestinian aggressor.
Mr. Fuld was born in New York, but spent most of his life in Israel, where he was friends with his family in the early nineties.
"Ari Fuld was a passionate defender of Israel and an American patriot," said US Ambassador David Friedman on Twitter. "He represented the best of both countries and will be missed."
Josh Hasten, a friend of Mr. Fuld, said he wanted to show what he saw as the realities of life in Israel.
"He was always on the street," Mr. Hasten said, asking if he should provide medical supplies to Israeli forces or drive them to an attack site for social media coverage.
