TEL AVIV, June 30 (Reuters) - Israeli Prime Minister Benjamin Netanyahu on Tuesday visited Lebanese territory occupied by the Israeli military, telling soldiers that Israel would not withdraw from the country's south as long as Iran-backed Hezbollah continued to pose a threat. It was the first visit by Netanyahu to occupied Lebanese territory since the Israeli and Lebanese governments reached a security agreement last Friday mediated by the United States under which Israel will hand over two areas to Lebanon's army.
