Sputnik News- Moscow welcomes US participation in Astana talks on Syrian crisis, but Iran's position is complicating the issue, according to Kremlin spokesman Dmitry Peskov.

Russia welcomes possible US participation in�Astana talks on�Syria, but�Iran's position is complicating the issue, Kremlin spokesman Dmitry Peskov told BBC in�an interview.

�We will welcome that [US participation in�Astana talks]. The situation is very complicated. You know that there is also Iran like�a very important player in�the Syrian issue. Iranians are not welcoming this. So it is a very complicated issue for�a very careful play,� Peskov said.

The peace negotiations on�Syria will take place on�Monday in�Astana, Kazakhstan.

The Syrian opposition groups agreed to�attend the talks brokered by�Russia, Turkey and Iran as�an attempt to�end the six-year civil war in�the country, which sees government forces fighting against�a number of�opposition and terrorist groups, including the Islamic State, which is banned in�Russia as�other states worldwide.

On Tuesday, Syria's Permanent Representative to�the United Nations Bashar Jaafari confirmed in�an interview with�Sputnik that he would lead the Syrian government�s delegation at�the upcoming talks.

Peskov also stated that any deals on�Syria are unlikely to�be reached at�the upcoming Astana talks on�Syrian crisis settlement, as�too many parties are involved in�the process.

�Any deals are unlikely to�be reached there, as�too many parties are involved in�the process,� Peskov said.

The abundance of�parties involved in�the upcoming talks in�Astana, to�take place on�January 23, may jeopardize the harmony of�negotiations, the spokesman added.
