Iran, Iraq and US Squabble Over Responsibility for Isis Advances

Rival powers and allies have traded barbs and accusations over the recent successes of Islamic State. A week after the militant group seized Ramadi in Iraq and Palmyra in Syria, and amid warnings that it may execute hundreds of hostages captured in its latest battles. The war of words highlighted disagreements between the US, Iraq and Iran over how to combat Isis. Months of air strikes have failed to check its advances. The commander of Iran’s Quds Force, the external operations arm of the Revolutionary Guards, said the US had “no will” to fight Isis. His comments came a day after the US defense secretary, Ashton Carter, told CNN Iraqi forces had shown “no will to fight” Isis and had fled in Ramadi despite outnumbering the militants.
