The UN says it hopes to start delivering aid to some besieged areas in Syria within the next 24 hours. The move comes shortly after world powers agreed to push for a cessation of hostilities in a week's time. Some Syrian cities have been cut off from humanitarian aid for more than a year because of fighting in surrounding areas. More than 250,000 people have been killed and 13.5 million displaced in almost five years of fighting in Syria. A new UN task force to co-ordinate the distribution of the aid is expected to convene in Geneva later. "The UN system has been geared to deliver this aid all along, especially to besieged areas, and that's precisely what's going to be discussed today: how to start, and when to start," UN spokesman Ahmad Fawzi said. "We hope to start as early as tomorrow, immediately after the meeting, decisions will be taken to roll the aid in, especially to besieged areas that need it", he added. The plan to deliver aid was part of a package of measures agreed by the 17-member International Syria Support Group (ISSG) in Munich on Friday. The group also agreed to seek a nationwide "cessation of hostilities" in Syria to begin in a week's time. The halt will not apply to the battle against jihadist groups IS and al-Nusra Front. The Syrian government has not yet responded, though a key rebel coalition welcomed the announcement. "If we see action and implementation on the ground, we will be soon in Geneva," Salim al-Muslat told reporters, referring to UN efforts there to get peace talks between the Syrian government and rebels off the ground. The announcement comes as the Syrian army, backed by Russian air strikes, advances in Aleppo province. The move threatens to encircle tens of thousands of civilians in rebel-held parts of the major city of Aleppo. Planned peace talks between the Syrian government and opposition groups in Geneva collapsed earlier this month. US Secretary of State John Kerry admitted the ceasefire plan was "ambitious" and said the real test would be whether the various parties honoured the commitments. "What we have here are words on paper, what we need to see in the next few days are actions on the ground," he said. US Defence Secretary Ash Carter told the BBC that Russia was "still way off track on Syria". "More broadly in Syria they said they would come in and fight ISIL and they didn't, instead they joined the civil war and fuelled the civil war", he said. NATO Secretary-General Jens Stoltenberg also sounded a similar note of caution. "Air strikes of Russian planes against different opposition groups in Syria have actually undermined the efforts to reach a negotiated, peaceful solution" he said. Russia insists it only targets extremist groups within Syria. Russian Foreign Minister Sergei Lavrov said there were "reasons to hope we have done a great job today". An earlier proposal from Russia envisaged a truce starting on 1 March. What has been agreed? -To try to immediately step up aid deliveries to besieged and hard-to-reach areas in Syria. -For a US/Russia-led task force to work to achieve a "cessation of hostilities" across Syria beginning in one week's time. -"Cessation of hostilities" will exclude action against so-called IS group, jihadist group al-Nusra Front and other UN-designated terrorist groups. -To work towards an eventual ceasefire and implementation of a UN-backed plan for political transition in Syria.
