Israeli troops in southern Lebanon detained four men yesterday for questioning in what appeared to be the first arrests since a ceasefire ended the war with Hizbullah. An Israeli patrol south of the village of Aita as-Shaab, the scene of heavy clashes during the 34-day conflict, detained the men yesterday afternoon, the Israeli military said. It said the men were armed, though it was not clear if they were members of the Hizbullah militia. "We still have security responsibility for that area," a spokeswoman said. "There was a patrol south of Aita as-Shaab that identified four armed men. They are being questioned in that location." The military said the men had been detained during a regular patrol.
