>> Stuck in no man's land, two aid convoys carrying flour and food stranded on the Turkish border heading for the Syrian city of Aleppo. This on the third day of a cease fire brokered by the US and Russia, an unprecedented collaboration between the two Cold War foes. Under the deal, Washington and the Kremlin aim to reduce violence before moving to coordinate military strikes against the Nusra Front and Islamic State.
But Reuters Tom Miles outside the UN's Geneva office says that could be problematic.>> Separating the opposition from the banned Nusra group is gonna be very, very difficult. The opposition say, we're in the same trenches. We share operations rooms. We're all fighting for the same cause. But the Americans and the Russians and the UN say the Nusra Front is a banned terrorist group.
Under the terms of the peace deal that's been struck by the Americans and the Russians, they're fair game and they can be targeted, they can be bombed by the Americans and by the Russians.>> Aid is badly needed. The United Nations estimates well over half a million people are living under siege In Syria.
Both superpowers now pinning all their hopes on the peace deal which they call a last chance to keep Syria together.
