Firefighters and army experts are calculating the risks of entering a residential block that was destroyed by fire in the eastern Spanish city of Valencia, killing four people and leaving 14 missing.

Valencia mayor Maria Jose Catala said that both the danger of the 14-storey building collapsing and the continuing intense heat from the fire were preventing emergency workers from getting in to search for possible survivors.
