"Escalation on the ground does not very much differ from how the situation was before. It is an informational rather than actual escalation." Jamil said Wednesday.
He added that according to the Hmeimim center on reconciliation, the number of ceasefire violations has not changed considerably recently.
"There have been, and there still are some difficulties. But it [cessation of hostilities] is holding," Jamil said.
The Moscow-Cairo opposition group believes that intra-Syrian negotiations should continue and UN Special Envoy for Syria Staffan de Mistura should not react to the provocation from the Saudi-backed opposition, according to Jamil.
On Monday, the High Negotiations Committee (HNC) delegation suspended its participation in the talks, blaming the government for the ongoing fighting in Syria.
"Mistura said that on Friday he will review the (current round of) talks and will decide what to do further. We told him that we think this round should continue, and he should not fall to the pressure and blackmailing of others," Qadri Jamil told Sputnik.
"The process is going on. Let those who want to boycott it boycott it. It will not have any influence on the negotiation process," he said.
A US-Russia-brokered ceasefire came into force across Syria on February 27. It does not apply to terrorist groups such as Daesh and the Nusra Front, both outlawed in several countries, including Russia.
