UN forces stationed in Lebanon are playing down illegal Hizbullah activity near the Israeli border in their reporting to the Security Council, government officials said Monday. The officials said that the Islamic group has beefed up weapons' stockpiles in south Lebanon since the Second Lebanon War. The UN forces stationed in the border area are not reporting sightings in the area of armed Hizbullah militants to the Security Council, they said. The officials spoke on condition of anonymity Monday due to the sensitive diplomatic nature of the comments. The UN-brokered cease-fire that ended the war bars Hizbullah fighters from a buffer zone in south Lebanon patrolled by international peacekeepers.
