The two suspects were identified as Jamil Khalifa and Ismat Matawia, both of Hebron.
Israeli army officers identified the Jewish victim as Dan Vargas, a 29-year-old resident of Kiryat Arba, an Israeli settlement on the outskirts of Hebron.
A security guard at a power station in the Israeli-controlled portion of Hebron, Vargas was a married father of one and was expecting a second child.
Army officials said they believed Vargas had left work when he was intercepted by the gunmen. He was shot at close range before his body was dumped on a roadside from a speeding car.
Hours after his murder, police found the body of a Palestinian man near the Jewish settlement of Itamar, east of Nablus.
The body of 68-year-old Mohammed Zalmout, of Beit Furik, was found murdered at the foot of an olive tree. He was bludgeoned to death with a rock.
The attacks came one day after Prime Minister Benjamin Netanyahu returned from the United States following the signing of the Wye Memorandum.
About 350 Jewish demonstrators took to the street Monday night outside the prime minister’s residence in Jerusalem, where 21 youths were arrested. Protesters chanted slogans more familiarly heard at left-wing demonstrations: “Bibi’s a traitor,” “Bibi is a failure,” “Bibi go home,” and “This is terror, not peace.”
One protester wore a yellow shirt with a picture of Rabbi Meir Kahane that read: “We are all Kahane.”
Meanwhile, Palestinians in Nablus clashed with Israeli troops during Zalmout’s funeral Tuesday. Other outbreaks of rioting occurred throughout the West Bank.
