ROME (Sputnik) — On Sunday, Alloush announced his resignation citing the failure of negotiations in Geneva to bring a political settlement in Syria.
"All in all it complicates the whole process, including progress in resuming dialogue between the Syrian sides," Gatilov told journalists.
According to the Russian official, common approach shared by all opposition groups is a must for negotiation process.
"When opposition is in disarray, represented by several groups in Geneva, talks are hardly efficient," Gatilov said.
The participants of the UN-mediated talks include the government and three opposition groups — the Riyadh-formed HNC, the Moscow-Cairo and the Hmeimim groups — to negotiation table in Geneva. After the latest round of Geneva talks held on April 13-27 the HNC withdrew citing lack of progress and numerous ceasefire violations.
