"We have not received an invitation yet. It could be that the meeting will be held by major international actors – Russia, the US and others – without Syrians," Abd Salam Ali, a PYD member, told RIA Novosti in Moscow.
Russian Foreign Minister Sergei Lavrov and US State Secretary John Kerry are due to attend the meeting. The PYD member said the Kurds expect the ISSG meeting to focus on Syria’s future political system, including outlooks for federalization.
In mid-March, Syrian Kurds announced the creation of a federal region in the country's north – the so-called Federal Democratic System of Rojava and Northern Syria, prompting condemnation from the international community.
