Foreign Ministry spokesman Jihad Makdissi stressed, however, that Damascus would not use its unconventional arms against its own citizens. The announcement comes as Syria faces international isolation, a tenacious rebellion that has left at least 19,000 people dead and threats by Israel to invade to prevent such weapons from falling into rebel hands.

Syria's decision to reveal the long suspected existence of its chemical weapons suggests a desperate regime deeply shaken by an increasingly bold revolt that has scored a string of successes in the past week, including a stunning bomb attack that killed four high-level security officials, the capture of several border crossings and sustained offensives on the regime strongholds of Damascus and Aleppo.

Syria is believed to have nerve agents as well as mustard gas, Scud missiles capable of delivering these lethal chemicals and a variety of advanced conventional arms, including anti-tank rockets and late-model portable anti-aircraft missiles.

A senior U.S. intelligence official said Friday, July 20, 2012, the Syrians have moved chemical weapons material from the country's north, where the fighting was fiercest, apparently to both secure it, and to consolidate it, which U.S. officials considered a responsible step.

But there has also been a disturbing rise in activity at the installations, so the U.S. intelligence community is intensifying its monitoring efforts to track the weapons and try to figure out whether the Syrians are trying to use them, the official said on condition of anonymity to discuss the still-evolving investigation.
