"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 said on Thursday.
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.
She also accused some members of the coalition as "financial and military supporters of terrorists in Iraq and Syria". REUTERS
