Israeli soldiers arrested the mother of 19-year-old Palestinian terrorist Omar al-Abed Tuesday on charges of “aggravated incitement,” following her son’s fatal stabbing of an Israeli father and two of his adult children last Friday night in the Samaria community of Halamish, amid escalating tension over Jerusalem’s Temple Mount.

Following the gruesome attack in the home of the Salomon family, the terrorist’s mother, Ibtisam al-Abed, said in a video that was widely circulated on social media that she was “proud” of her son. Further, the Abed family celebrated the terror attack by handing out sweets to guests at their home in Kaubar. The IDF said the terrorist’s mother incited “more attacks on Jews.”

The Halamish terror attack came on the heels of a Palestinian-incited “day of rage,” amid tension over Israel’s now-removed metal detectors at Jerusalem’s Temple Mount. The Jewish state had bolstered security following the July 14 Arab terror attack that killed two Israeli Druze policemen near the holy site.

The three victims in Friday night’s Halamish terror attack were Yosef Salomon, 70, his daughter Chaya, 46, and his son Elad, 36. Yosef’s wife, Tova, 68, was wounded and rushed to Jerusalem’s Shaare Zedek Medical Center, where she underwent surgery Saturday morning.

“The scenes of a bloodbath that greeted us when we arrived on Saturday evening at the Salomon home shocked us all to the core—even the most veteran ZAKA volunteers,” Yehuda Meshi Zahav, chairman of the ZAKA emergency response group, told JNS.org. “It was painstaking work to gather up so much blood, but we were determined to finish so that the victims could be buried as soon as possible, in keeping with Jewish law.”

Several hours before initiating Friday night’s attack, Omar al-Abed wrote on Facebook, “There is no life after what is seen in [the Temple Mount compound’s] Al-Aqsa [mosque].” He added, “All I have is a sharpened knife, and it responds to the call of Al-Aqsa…God will take revenge on you.”

The terrorist knocked on the door and burst into the Salomon family’s home as they gathered around the table for a festive Shabbat meal, celebrating the birth of a new grandson. As Abed entered, armed with a knife, Elad’s wife rushed a group of children to safety in a nearby room, holding the door shut while calling the police. The terrorist stabbed four members of the family before a neighbor, who overheard screaming, ran over and shot him.

Abed, who was treated for his wounds at Rabin Medical Center in Petah Tikva, is in the Israeli defense establishment’s custody. He was arrested several months ago by Palestinian Authority security forces on suspicion of plotting terror attacks. An Israeli military official said the terrorist’s parents were known supporters of the Palestinian terror group Hamas. Further, the IDF and Israel’s Shin Bet security agency arrested 29 Hamas members, including some of the terror group’s senior officials, in overnight raids in the disputed territories.

Early Saturday morning, IDF troops raided the Abed family home in the village of Kaubar, searching for weapons and additional suspects. The IDF surveyed the home for demolition and arrested the terrorist’s brother, 21-year-old Monir al-Abed, on suspicion of aiding Omar in the attack.

“The wave of detentions…was part of the preventive efforts of the Shin Bet security service and the Israel Defense Forces against the terrorist organizations, particularly during the past week and due to the tension surrounding the Temple Mount and the unrest in the area,” the Shin Bet said.

When news of the Halamish terror attack reached Hamas-controlled Gaza, jubilant Palestinians took to the streets to celebrate and hand out sweets. Hamas praised the “heroic” attack, while Palestinians in Gaza fired a rocket at the Israeli city of Ashkelon early Sunday morning. The rocket “exploded mid-air” and caused no injuries or damage, the IDF said.

Palestinian Authority (PA) President Mahmoud Abbas, meanwhile, announced the cancellation of security coordination with Israel as part of a general freeze in communication with the Jewish state. It was the first freeze of Israel-PA security cooperation announced by Abbas since he assumed office in 2005.

Israeli Defense Minister Avigdor Lieberman said Israel will manage without coordinating security with the PA, slammed Abbas for failing to condemn Friday night’s terror attack. “He’s not a partner, he’s not looking for peace,” Lieberman said of Abbas, Yedioth Ahronoth reported.

Regarding the escalation of Israeli-Palestinian tension, the JCPA’s Daniel Diker said, “Any time you have terror attacks against Israel, which puts Israel in the position of having to defend itself in terms of passive and active measures, it always looks like things are escalating.”

“We’ve learned from experience,” he said, “that these things don’t necessarily indicate that there’s going to be a major war.”
