On August 31st, the brilliant anonymous German intelligence analyst who blogs as "Moon of Alabama" headlined "Syria – Coordinated Foreign Airstrike Kills Leaders Of Two Al-Qaeda Aligned Groups", and he reported that,"Some three hours ago an air- or missile strike in Syria's Idleb governorate hit a meeting of leaders of the al-Qaeda aligned Haras-al-Din and Hay'at Tahrir al-Sham (HTS) aka Jabhat al-Nusra. Both were killed. It is likely that leaders of other Jihadist groups were also present. The hit completely destroyed a Haras al-Din guesthouse or headquarter. The Syrian Observatory says that more than 40 people were killed in the strike. The hit will make it much easier for the Syrian army campaign to liberate Idleb governorate."
At long last, Syria's army and Russia's air force are no longer being threatened with World War III by the US and its allies if they proceed to destroy the tens of thousands of Al-Qaida-led jihadists whom the US had helped to train and arm(and had been protecting in Syria ever since December 2012) in order to overthrow Syria's non-sectarian Government and replace it by a fundamentalist-Sunni Government which the royal Sauds who own Saudi Arabia would appoint. All throughout that war, those Al-Qaeda-led 'moderate rebels' had been organized from the governate or province of Idlib (or Idleb). But now, most (if not all) of their leadership are dead.
