The leader of the regional government of Valencia, Spain, announced a three-day mourning period on Friday after a fire at a high-rise residential complex killed at least four people.

Firefighters and police responded to the scene shortly after 5:30 p.m. on Thursday, when within half an hour the fire destroyed the two entire buildings, one of which was 14 stories high.

At least 14 people have been reported missing, and authorities said the number of dead and missing could still rise, because high temperatures inside the charred structures have prevented emergency workers from searching inside.

At a news conference Friday morning, Carlos Mazón, president of the regional government, praised the work of first responders and noted that seven of those injured in the fire were firefighters.

Valencia City Council said in a statement that a aid point had been set up in a nearby building to offer practical and psychological support to surviving residents. Another meeting point was to offer information and support to the relatives of missing people, he added.
