__________________________________________Syria has approved aid deliveries to seven besieged areas, but the UN special envoy Staffan de Mistura said the UN had to have access to all Syrians in need. Our diplomatic correspondent James Robins reports. "This is an increasingly tense week after key world powers including Russia agreed to work towards a partial ceasefire in Syria. But neither the Syrian government nor opposition forces were involved and the UN envoy Staffande Mistura is meeting Syria's foreign minister in Damascus trying to persuade his government to stop fighting and allow unhindered humanitarian access to all besieged areas. There are signs that aid will be allowed into some besieged areas over the next few days, but it is hard to see an end to the fighting. __________________________________________敘利亞已同意聯合國對其境內七個被戰火圍困的地區運送援助物資,但聯合國特使斯坦芬?德?米斯圖拉表示,敘利亞必須對聯合國敞開其境內所有急需援助的地區.我們的外交記者詹姆斯?羅賓斯報道."隨著幾個主要的世界強國包括俄羅斯同意執行局部地區?；饏f議后,這周局勢也不斷緊張起來.但敘利亞政府和其反對勢力都沒有卷入其中.聯合國特使米斯圖拉正在大馬士革會見敘利亞外交部長試圖說服其政府停戰并允許聯合國對其境內所有被戰火圍困的地區提供人道主義援助.有跡象表明,之后幾天里敘利亞境內部分被戰火圍困的地區將接受援助,但停戰的希望仍然渺茫."
