France and Britain called on the Syrian regime and its ally Russia on Thursday to respect Syrian cessation of hostilities deal and immediately end attacks on opposition groups, saying all sides had to fully implement the deal and allow free access to besieged areas.
"We ask all sides that are committing human rights violations, including Russia and the Syrian regime, to put an immediate end to the attacks against moderate opposition groups," a joint statement said after a Franco-British summit.
The statement also said that all attacks against civilians and medical staff had to stop and the Syrian regime ans its allies should stop their "march to Aleppo, which compromised peace prospects and threatened to dramatically worsen the refugee crisis and benefit Islamic State [DAESH]."
Kremlin stated on Thursday that Russian President Vladimir Putin would hold phone talks with European leaders on Syria on Friday. It added that the talks would involve British Prime Minister David Cameron, French President Francois Hollande and German Chancellor Angela Merkel.
France and Britain said that they would apply pressure on Russia with regard to the Syrian crisis during when they hold the conference call with Putin.
"We will discuss Syria with Chancellor (Angela) Merkel and President (Vladimir) Putin on Friday," Cameron said after the summit with Hollande.
"Russia must end its attacks against Syrian civilians and the moderate opposition," he added.
Hollande echoed those remarks saying that "We want to pressure all the protagonists in the conflict, including Russia."
The two leaders also urged Russia to use its influence on separatists in eastern Ukraine to stop the violence there and called on the Ukrainian government to unify its efforts to implement reforms.
The cessation of hostilities deal was agreed on by Washington and Moscow on Feb. 27. It is the latest in a series of diplomatic efforts ostensibly aimed at ending the conflict, which will soon enter its sixth year.
DAESH and Al Qaeda’s Syria affiliate, Nusra Front, which are designated terrorist organisations by the UN Security Council, were not included in the agreement.
