BETHESDA, Md. (AP) -- Crews are scrambling to rescue motorists who are stranded in at least four feet of water following a massive water main break just outside Washington, D.C.

Television images showed two people in a minivan climbing into a basket that was lowered from a helicopter flying overhead.

Montgomery County fire department spokesman Pete Piringer says at least a dozen people have been rescued from their vehicles so far. There were no injuries reported so far.

The water main break occurred amid frigid temperatures in the region.
