Syria congress delayed as Russia talks with rebel groups

Regime-backer Moscow has invited 1,600 delegates to the meeting in the Black Sea resort of Sochi as part of a broader push to consolidate its influence in the Middle East and start hammering out a political solution to the conflict.

But Syria's main opposition group and Kurdish authorities said they would boycott the event, while on Tuesday separate rebel representatives were at Sochi airport but refused to come to the congress before Russia met demands.

"There have been some problems with an armed opposition group arriving from Turkey, which said its participation depended on additional requirements," Artem Kozhin of the Russian foreign ministry said in comments reported by the TASS news agency. The Russian and Turkish foreign ministers spoke twice on the phone in a bid to resolve the problem, he said.

A rebel source said that Russia had promised to change or remove the symbol of the congress, which features only the Syrian regime flag.

But the airport, the road to the conference centre and the congress hall itself were still decorated with banners and billboards bearing the logo when the rebels arrived last night, leading to hours of ongoing negotiations. The main aim of the talks is to establish a committee to create a post-war constitution for Syria with United Nations backing, according to a draft statement seen by AFP.

Moscow said Syrian society would be fully represented at the meeting -- the first of its kind held in Russia -- but almost all confirmed delegates are from either President Bashar al-Assad's ruling Baath Party, allied movements or the regime's "tolerated opposition". The Syrian Negotiation Commission (SNC), the country's main opposition group, said following two days of UN-led talks in Vienna last week it would not attend the Sochi congress.

The SNC accused Assad and his Russian backers of continuing to rely on military might and showing no willingness to enter into honest negotiations.

Authorities from Syria's Kurdish autonomous region said at the weekend they would also boycott the event because of the ongoing Turkish offensive on the Kurdish enclave of Afrin.

Clashes and air strikes again hit the border region of Afrin on Monday, with new civilian casualties reported.

Turkey, which supports Syrian rebels vying for Assad's ouster, is co-sponsoring the

congress along with regime-backer Iran. However, members of the opposition were at the event in an individual capacity, while the Kremlin's special envoy on the Syria peace process Alexander Lavrentyev said some Kurds would also attend individually.

The UN's Syria peace negotiator Staffan de Mistura was expected to participate, despite fears among Western powers that Russia is seeking to undermine a separate track of UN- backed Geneva talks with a view to carving out a settlement that strengthens its ally Assad.
