The unrest came hours after the arrest of two Palestinians in connection of the murder of three Israelis, who were axed to death.

In the southern West Bank, a Palestinian infiltrated the Tekoa settlement before being shot by a resident, the Israeli army claimed.

“Soldiers were dispatched to the scene and are searching the area for additional suspects,” a statement from the military said.

The Palestinian health ministry said Motasem Attalah, 17, was killed.

A short time earlier, a 19-year-old Palestinian without an entry permit for Israel stabbed a police officer outside the Old City in east Jerusalem before being shot and “neutralised” by forces at the scene, Israeli police said in a statement.

Earlier Sunday, Israeli soldiers shot dead a Palestinian who tried to enter Israel through the Jewish state’s barrier in the north of the occupied West Bank.

Soldiers “identified a (person) trying to cross the security barrier” near Tulkarem, an army statement said. “The force shot at him in accordance with procedures. The suspect was taken for medical care.”

A spokesman for the Sheba hospital in central Israel told AFP the Palestinian had died of his wounds, with the Palestinian health ministry identifying the deceased as Mahmud Eram.

Security forces had earlier arrested two Palestinians suspected of carrying out an axe attack in central Israel on Thursday that left three dead.

The security services – who previously identified the suspects as Assad Yussef al-Rifai, 19, and Subhi Imad Abu Shukair, 20 – said the pair were spotted hiding in a bush near a quarry, just outside the central town of Elad, where the attack took place.

The perpetrators had entered Israel through the porous barrier with the West Bank, an Israeli military official said earlier, calling their infiltration a “failure” of the army.

Bloody cash

Thursday’s attack in Elad, populated by mainly ultra-Orthodox Jews, was the sixth deadly incident targeting Israelis since March 22.

Witnesses said two assailants leapt from a car swinging axes at passers-by, leaving three dead and four wounded, before fleeing in the same vehicle.

The manhunt included the police, domestic security agency and the army, along with helicopters and drones, the security forces said.

The Israeli military official said bloody banknotes, presumably dropped by the suspects in flight, helped lead the forces to where the pair were hiding.

Forces scanning the area noticed a bush “that looked a bit different”, said the official, who spoke to reporters on condition of anonymity.

Israel has identified the three killed Thursday as Yonatan Habakuk, 44, and Boaz Gol, 49, both from Elad, as well as Oren Ben Yiftach, 35.

The bloodshed unfolded as Israel marked the 74th anniversary of its founding, which has previously been a tense day in the Israeli-Palestinian conflict.

Al-Aqsa excesses

The Elad killings followed a tense period in which the Muslim fasting month of Ramadan, the Jewish festival of Passover and the Christian holiday of Easter overlapped.

Tensions have boiled over into violent clashes between Israelis and Palestinians at the Al-Aqsa mosque compound, a highly contested site in Jerusalem’s Israeli-annexed Old City.

Palestinian president Mahmud Abbas had condemned the Elad attacks, warning that the murder of Israeli civilians risked fuelling a broader cycle of violence.

But Hamas, which controls the Gaza Strip, praised the attack – as did the Gaza-based Islamic Jihad group – calling it a consequence of unrest at Al-Aqsa.

The Islamic Jihad called the attackers “heroes” and said their arrest would not “discourage” people from continuing their violent resistance.

Hamas said the attack “demonstrates our people’s anger at the occupation’s attacks on holy sites”.

A string of attacks since March 22 have killed 18 people, including an Arab-Israeli police officer and two Ukrainians.

Two of the deadly attacks were carried out in the Tel Aviv area by men that Israeli authorities say were Palestinians.

A total of 29 Palestinians and three Israeli Arabs have died during the same period, among them perpetrators of attacks and those killed by Israeli security forces in West Bank operations.
