Members of the Syrian Social Nationalist Party hold portraits of Syrian President Bashar al-Assad during a demonstration supporting his regime and against a possible military strike in Syria on September 8, 2013 in Beirut. US President is pressing Congress to approve military action against the Syrian regime in response to an alleged August 21 attack with chemical weapons. The Pentagon is readying more intense and longer attacks on Syria than originally planned, set to last three days, the Los Angeles Times reported. War planners now aim to unleash a heavy barrage of missile strikes to be followed swiftly by additional attacks on targets that may have been missed or remain standing after the initial launch, the Times cited officials as saying.
