A Canadian-Israeli geographer, Professor Razi Salakh, has been under arrest for the past 18 days on suspicion of spying on behalf of terror groups, the Shin Bet (Israel Security Agency) announced on Wednesday. The man, a Beduin, does not live in Israel, but his family lives in the Nazareth area. The Shin Bet and Galilee police apprehended the suspect as he was photographing military installations in the North. The Acre Magistrate's Court extended his remand by four days and released the story for publication. In April, Lt.-Col. Omar el-Hayib, a senior Beduin military officer, was convicted in a military court of spying on Israel on Hizbullah's behalf. El-Hayib, who was arrested in October 2002, was convicted of espionage, contact with a foreign agent and drug dealing but was acquitted of a charge of treason. From the village of Beit Zarzir in the North, El- Hayib, 43, served in the IDF's Northern Command and was responsible for the recruitment of Beduin soldiers. According to the indictment, el-Hayeb held contacts with foreign Lebanese agents from 2002 on dozens of occasions. The prosecution claimed he transferred sensitive information regarding the movements and security surrounding then-OC Northern Command Maj.-Gen. (res.) Gabi Ashkenazi to Lebanon, in addition to tank movements along the border as well as other military secrets. In exchange, el-Hayeb received cash payments as well as dozens of kilograms of heroin and hashish.
