Syria conflict: UN invites Iran to Geneva II talks

Iran has accepted an invitation to take part in preliminary Syrian peace talks this week in Switzerland, the UN Secretary-General has confirmed.

Ban Ki-moon said he had received assurances that Iran would play a positive role in securing a transitional government.

But Syria's main opposition group said it would withdraw from the talks unless Mr Ban retracted the offer to Iran.
