JERUSALEM, May 14 (JTA) — Israeli forces killed one Hezbollah gunmen and wounded another in a clash on the edge of the southern Lebanon security zone Wednesday. No Israeli troops were injured. Earlier this week, four Hezbollah gunmen were killed when a force of some 40 fighters were repulsed in an effort to take over a position of the South Lebanese Army in the security zone. One Israeli soldier and three South Lebanese Army troops were wounded in the clash. In a separate development, two Israel Defense Force soldiers sustained light to moderate injuries in an accident when an armored personnel vehicle swerved from its path and hit them during a patrol in the security zone.
