Iran: anti-Islamic State coalition 'shrouded in serious ambiguities'

Reclusive leader of militant Islamic State Abu Bakr al-Baghdadi made what would be his first public appearance at a mosque in Mosul,

ANKARA - Iran said on Thursday the emerging international coalition to battle Islamic State militants was "shrouded in serious ambiguities", Iranian state television reported.

Islamic State fighters have seized major Iraqi cities and towns bordering Iran and Tehran has expressed concern about their rapid advance and the upsurge in violence.

"The so-called international coalition to fight the ISIL group ... is shrouded in serious ambiguities and there are severe misgivings about its determination to sincerely fight the root causes of terrorism," Foreign Ministry spokeswoman Marzieh Afkham was quoted by state TV as saying.

She did not mention specifically a call by US President Barack Obama for a broad coalition to root out Islamic State in Iraq and Syria and said some coalition members were "financial and military supporters of terrorists in Iraq and Syria".

Obama also said on Wednesday that he had authorised US air strikes for the first time in Syria and more attacks in Iraq in an escalation of a campaign against Islamic State.
