NABLUS – Israeli forces have detained the wife of an Islamic Jihad leader who is being held in administrative detention, Israeli and Palestinian sources said Monday. Palestinian security sources in the northern city of Jenin said Nawal Saadi, 52, was arrested at her home in the city's refugee camp in the early hours of Monday morning. An Israeli army spokeswoman confirmed the arrest. “She was arrested this morning by border police and transferred to the custody of security forces, Israeli police, for questioning," she said. There were no details on why Saadi was arrested. Her husband Bassam Saadi, a local Islamic Jihad leader, has been detained without charge by Israeli authorities for more than a year under an administrative detention order. Israel regularly carries out arrest raids throughout the West Bank, including in areas under full Palestinian security control. Last week, troops arrested five Palestinians, including two men with ties to the Islamic Jihad movement. Meanwhile, a Palestinian man apparently suffering psychiatric problems was killed by Israeli troops after he approached Gaza's border fence, Palestinian medical sources said Monday. The 20-year-old man, named as Ahmed Al-Nabaheen, was injured Sunday evening, but the Israeli army refused to allow Palestinian ambulances to the scene to transport him, the medics said. His body was recovered Monday morning. An Israeli army spokeswoman confirmed that a “suspect" had approached the border area. “The soldiers spotted him and fired warning shots in the air, but he continued to approach Israeli territory," she said. “The soldiers then fired in his direction and achieved a hit." Israel's military maintains a buffer zone that runs several hundred meters inside the Gaza Strip, along the border with Israel, with troops opening fire on anyone who enters the area. – Agencies
