伊朗否认曾对伊拉克伊斯兰国发动空袭
The Iranian government is rejecting US reports that Iranian forces launched airstrikes against Islamic State targets in eastern Iraq this week.
美国曾报道伊朗武装本周对伊拉克东部伊斯兰国进行过空袭，伊朗政府对此予以否认。
Word of this has also created speculation Iran may be cooperating, in one form or another, with the US-backed coalition which has been battling the Islamic State in both Iraq and Syria.
The Iranian side is downplaying this suggestion.
Iranian Foreign Ministry spokesperson Marzieh Afkham.
"There has been no change in the Islamic Republic's policies regarding fighting terrorists and helping the Iraqi government. The news about cooperation of Iran with military forces of the other countries to fight Islamic State are not accurate"
US Secretary of State John Kerry helped fuel this suggestion of Iran's support for the coalition by saying he was not going to confirm or make any announcements on the issue.
At the same time, he did say any action taken by Iran against the Islamic State would be "positive".
