Damascus: Syrian opposition groups are meeting in Madrid to compile a draft political solution to the conflict.
The talks, which entered a second day on Tuesday, include Moaz al-Khatib, who resigned last week as leader of the Syrian National Coalition.
Khatib cited the failure of the international community to stop the conflict as the reason he stepped down.
The Spanish foreign ministry said "various movements" of the opposition to Syria's President Bashar al-Assad were involved in the talks, in addition to the coalition, which is the main opposition bloc.
Pressed back by army advances, Syria's opposition is under international pressure to enter into dialogue with Assad's government.
More than 80,000 people have been killed in the conflict, according to the UN, and 1.5 million people have fled the country since the uprising began in March, 2011.
