JERUSALEM (AFP) - Israel has arrested the Palestinian head of Al-Jazeera's Kabul office, accusing him of belonging to Hamas and contacting its military wing, the channel's Jerusalem bureau chief told AFP on Tuesday. Samer Allawi was arrested last Wednesday as he tried to cross to Jordan from the West Bank, where he had been visiting his family, Walid al-Omary said. On Tuesday morning, he was taken before an Israeli military court in the northern West Bank which extended his detention for another seven days. It accused him of "membership in Hamas" and having "contact with members in Hamas's military wing," Omary said after the court hearing.
