The Lebanese prime minister warned that his army will seize all weapons shown publicly in southern Lebanon, offering a sharp retort to a boast from Hezbollah's leader that his fighters are on the border with Israel and won't leave. A month into the UN cease-fire between Israel and Hizbullah, the United Nations said the truce is holding well, but the comments underscored growing friction between the Islamic militant group and the Lebanese government, which is led by opponents of Hizbullah's patron Syria. "I intend for the Lebanese army to prove its presence in the area south of the Litani River," Prime Minister Fuad Saniora told reporters Thursday after talks with Egyptian President Hosni Mubarak in Cairo. "We want this area to be under the army's and the Lebanese state's control. The army has all the authority to ban any armed appearances and confiscate those weapons," Saniora said.
