An opening speech by Russian Foreign Minister Sergei Lavrov, delayed by two hours because of ongoing negotiations, was interrupted both by cries of "Long live Russia!" and angry heckling from Syrian delegates. Reading out a letter from President Vladimir Putin, Lavrov called for the UN to play a leading role in any political settlement, following fears Russia is seeking to undermine separate UN-backed talks with a view to carving out a deal that strengthens Moscow's ally President Bashar al-Assad. Representatives of rebel groups flew into Sochi from Turkey late Monday but refused to leave the airport after seeing the symbol of the congress featured only the Syrian regime flag.
A rebel source told AFP that Russian hosts had promised to change the symbol, which was displayed on posters in the airport as well as billboards on the road towards Sochi, and in the congress hall itself.
