He said concerns are rising that aid won't be able to reach thousands of Syrian refugees sheltered in Arsal.

Lebanese aid organizations distributed a three-day emergency food supply to the neediest refugees in Arsal on Monday, a U.N. official said, but stressed that tens of thousands more had to rely on dwindling stocks within the town.

Arsal is a town of 40,000 Lebanese and 52,000 Syrian refugees for whom the road is a vital lifeline.
