NEW YORK (AP) — Federal regulators say Hurricane Sandy knocked out a quarter of the cell towers in an area spreading across ten states, and the situation could get worse before it gets better.

Many cell towers that are still working are doing so with the help of generators and could run out of fuel before commercial power is restored, the Federal Communications Commission says.

The landline phone network has held up better in the affected area, which stretches from Virginia to Massachusetts, the FCC says, but about a quarter of cable customers are also without service.
