Bassma Kodmani, a delegation member, told reporters on Friday that further discussions will be held to decide on the delegation list. The announcement came on the second day of a Saudi-sponsored meeting in Riyadh, where 140 opposition figures are gathered to unify their ranks before direct talks with Syrian President Bashar al-Assad's regime next week.

Dmitry Peskov, a Russian Presidential spokesperson, said Thursday that the Syrian national dialogue should involve all Syrian groups.
