Italian Premier Romano Prodi met Sunday with top Cabinet ministers to discuss Italy's involvement in a UN peace force in southern Lebanon. Prodi, interrupting his summer vacation, held talks at his Rome office with Foreign Minister Massimo D'Alema, Defense Minister Arturo Parisi and other top officials. Italy has repeatedly affirmed its willingness to participate in the international force, provided that there's a strong UN mandate. Prodi and D'Alema have expressed satisfaction over the U.N. Security Council resolution that seeks a full halt to fighting between Israel and Hizbullah guerrillas and authorizes a 15,000-member peacekeeping force in southern Lebanon. Prodi has said Italy's contribution would be "significant."
