Iranian Foreign Minister Mohammad Javad Zarif will attend multilateral talks on finding a political solution to the conflict in Syria in Vienna this week, a government spokeswoman has said.
It will be the first time Iran – an ally of President Bashar al-Assad – has attended such a summit with the US.
Representatives of Russia, Saudi Arabia and Turkey will also attend the talks.
Earlier, the US said an invitation had been extended to Iran – a move Syria’s Western-backed opposition questioned.
