IDF troops on Monday night killed a Palestinian gunman south of Jenin during a fierce exchange of fire with between three Palestinian operatives and an IDF patrol, Palestinian sources reported. The IDF said that an armed Palestinian opened fire at IDF troops operating in the area, and the troops returned fire. There were no casualties among the soldiers. It was unclear to which organization the gunman belonged. Earlier Monday, IDF troops arrested 26-year-old Tanzim operative Khatim Abdel Khativ in the Kalandiya refugee camp. Khativ was involved in planting a bomb at the Atarot Airport in 2002, and he also attempted to carry out several other attacks on IDF troops in the West Bank, the IDF said. In addition, Border Police arrested three members of Hamas near the Bir Zeit bridge on suspicion of attempting to kidnap Israelis in the West Bank, the Shin Bet (Israel Security Services) released for publication on Monday afternoon. Army Radio reported that the three, who were arrested in February, planned to use the kidnapped Israelis as bargaining chips for Palestinian prisoners. In a separate development, undercover border policemen arrested two Islamic Jihad operatives west of Jenin on Monday afternoon. The men were caught in a car, along with two other Palestinian youths who were detained for interrogation.
