Yemen is not the only country in which Saudi Arabia is taking a more vigorous role. Last week, President Bashar al-Assad of Syria suffered several defeats, the most important being the fall of the provincial capital Idlib, in northern Syria, to Jabhat al-Nusra which fought alongside two other hardline al-Qaeda-type movements, Ahrar al-Sham and Jund al-Aqsa. Al-Nusra’s leader, Abu Mohammed al-Golani, immediately announced the instruction of Sharia law in the city. Sent to Syria in 2011 by Isis leader Abu Bakr al-Baghdadi to create al-Nusra, he split from Baghdadi when he tried to reabsorb al-Nusra in 2013. Ideologically, the two groups differ little and the US has launched air strikes against al-Nusra, though Turkey still treats it as if it represented moderates.The Syrian government last week accused Turkey of helping thousands of jihadi fighters to reach Idlib and of jamming Syrian army telecommunications, which helped to undermine the defences of the city. The prominent Saudi role in the fall of Idlib was publicised by Jamal Khashoggi, a Saudi journalist and adviser to the government, in an interview in The New York Times. He said that Saudi Arabia and Turkey had backed Jabhat al-Nusra and the other jihadis in capturing Idlib, adding that “co-ordination between Turkish and Saudi intelligence has never been as good as now”. Surprisingly, this open admission that Saudi Arabia is backing jihadi groups condemned as terrorists by the US attracted little attention. Meanwhile, Isis fighters have for the first time entered Damascus in strength, taking over part the Yarmouk Palestinian camp, only ten miles from the heart of the Syrian capital.
