An Israeli undercover unit killed a Palestinian activist from the Al-Aqsa Martyrs Brigades in the northern West Bank city of Jenin, Palestinian security and medical sources said. Asaad Salah Khaliliyeh, 32, was shot dead in front of the Jenin municipality by plainclothed Israeli security forces traveling in a civilian vehicle, the sources said, according to AFP. The Palestinian was taken to hospital where he was declared dead. Khaliliyeh was also a member of the Palestinian police services. The head of the Al-Aqsa group in Jenin, Zaqaria Zubeidi, confirmed Khaliliyeh had been killed and promised bloody revenge. "Al-Aqsa Martyrs Brigades will retaliate for this operation and continue their resistance against soldiers and settlers," he told AFP. **Students Jailed for Shunning Israeli Army*** Five Israeli students have been sentenced to a year in jail for refusing to serve in the army. Calling themselves conscientious objectors, they accuse the Israeli Defence Forces of being an occupying army. One of the students, Noam Bahat, said: "This is not the highest price to pay. The Palestinians pay a higher price every day for the occupation which they have no choice over." A military court said the one-year jail term was aimed at deterring others from refusing to serve in the army for political reasons. Since the outbreak of fighting between Israelis and Palestinians in September 2000, more than 550 Israeli reserve soldiers have publicly declared their refusal to serve in the Palestinian territories. **PHOTO CAPTION*** Israeli men from right: Hagai Matar, Shimri Tzameret, Matan Kaminer, Noam Bahat and Adam Maor arrive at the Karmel military prison in Atilt near Haifa, Israel Wednesday Jan. 7, 2004 where they are expected to serve one year each for refusing to serve in the military because of Israel's occupation of the West Bank and Gaza Strip.
