Watch: Helicopter rescues elderly woman trapped by floods

Spain's military emergency unit has released footage of a dramatic rescue of an elderly woman who had been trapped by floods in the Valencia region.

Spain has issued another storm warning for part of the Valencia region devastated by floods that have killed at least 95 people, as rescuers scoured flooded fields and stranded cars for those still missing.

Local authorities have not disclosed how many people are still unaccounted for after Europe's deadliest floods in years, but Defence Minister Margarita Robles said late yesterday the death toll was likely to rise.

Rescue workers combed the wreckage of vehicles that were caked in mud next to roads or in flooded fields, with some using heavy machinery to clear debris from the streets, television footage showed.

The floods in Valencia battered the region's infrastructure, sweeping away bridges, roads, rail tracks and buildings as rivers burst their banks.
