"We hope that this plan will improve the situation in Syria," Clements told Sputnik on Tuesday.
"The situation in Syria is quite dire <…> We have been trying since very long time to get to the besieged areas. Hopefully, this will mean that we can actually get in and not just to deliver the [humanitarian] convoy and leave again, but to be able to have a sustained access," he said.
On Monday, US Secretary of State John Kerry and Russian Foreign Minister Sergei Lavrov announced an agreement on cessation of hostilities between the Syrian government of President Bashar Assad and the armed opposition factions had been reached. The agreement will come into force on February 27.
The deal between Russia and the US was approved by the International Syria Support Group (ISSG). During its meeting on February 12, the ISSG agreed a final communique calling for swift humanitarian access to all besieged areas in Syria, and set a one-week deadline for measures to be implemented toward the cessation of hostilities in the country.
