al-Assadi, spokesman of the Hashed al-Shaabi (popular mobilisation).
He was referring to the debacle of security forces when IS-led fighters swept across Iraq’s Sunni Arab heartland in June last year, bringing Iraq to the brink of collapse.
Some Iraqi forces were criticised for avoiding battle during the fall of Ramadi, which led Prime Minister Haider al-Abadi to call in the Hashed al-Shaabi.
He and Washington had opposed the mass deployment in the Sunni province of Anbar of militia groups with direct ties to Iran and a dubious human rights record.
However, the strategy of US-led coalition air strikes while the security apparatus gets revamped has failed to keep up with the pace of IS advances.
“At this time, the Hashed are Abadi’s best bet. I don’t think he has many options,” said Ayham Kamel, director for the Middle East and North Africa at the Eurasia Group.
Washington tried to remain upbeat after the loss of Ramadi and Palmyra, playing down the IS advance as tactical setbacks.
The Jihadists, who now control roughly half of Syria, reinforced their self-declared transfrontier “caliphate” by seizing Syria’s Al-Tanaf crossing on the Damascus-Baghdad highway late on Thursday.
Fabrice Balanche, a French expert on Syria, said “IS now dominates central Syria, a crossroads of primary importance” that could allow it to advance towards the capital and third city Homs.
The IS advance in both countries forced tens of thousands of civilians from their homes, sparking concern among humanitarian agencies.
IS on Friday also demonstrated its ability to strike beyond the heart of its “caliphate” when for the first time it claimed an attack in Saudi Arabia.
The suicide bombing, targeting worshippers at the main weekly Muslim prayers in Qatif, in the east of the kingdom, killed 21 people and wounded 81, Saudi authorities said.
The UN Security Council reacted by stressing that IS “must be defeated and that the intolerance, violence and hatred it espouses must be stamped out”.
“There has to be a common effort amongst governments and institutions, including those in the region most affected, to counter” the group, it said.
In Syria, despite a series of regime losses, President Bashar al-Assad saluted the “heroism” of some 150 soldiers and their families who escaped an almost month-long rebel siege of a hospital.
The group had been besieged inside the building in Jisr al-Shughur since the town in northwestern Syria fell to rebels including al-Qaeda’s local affiliate, on April 25. On Friday, most of those inside managed to escape just as rebel forces overran the hospital.
