Syria allows humanitarian aid to cut-off areas.
What does cut off areas mean in the previous sentence?
I don't know the details on the ground, but I imagine it means they allow humanitarian aid to reach areas that have been cut off by fighting or have actually been besieged. In news reports it is common for journalists to save words by using compound adjectives like that - preposing the adjective and suppressing the context (in this case, who was doing the cutting off and why).
