Italian troops, trucks and armored personnel carriers landed Sunday in Lebanon as the arrival of the first large contingent of international peacekeepers entered its second day after being delayed by rough seas south of the capital. U.N. peacekeeping spokesman Alexander Ivanko said more than 500 Italian soldiers had arrived and the remaining 500 were expected later in the day. In the southern city of Tyre, trucks and equipment rolled onto a beach from landing craft as Italian battleships floated offshore. Equipment and soldiers were also expected at Beirut's port and airport, the Associated Press reported.
