VALENCIA — Spanish rescuers are focusing their search for missing people on underground garages and a multi-story car park following last week's devastating floods in Valencia.

The death toll after a year's worth of rain fell in parts of the region last week now stands at 217.

A car park in the nearby town of Aldaia capable of holding thousands of vehicles, has become central to the search, but rescue teams have reportedly not yet found any bodies.

It comes as Spain's State Meteorological Agency (AEMET) placed part of the north-eastern Catalonia region on red alert for torrential rain, with its capital Barcelona experiencing flooding on Monday morning.

The car park at the Bonaire shopping centre in Aldaia was inundated during flash floods last week.

According to Spanish news agency Europa Press, police have confirmed that search teams did not locate any victims in the first 50 vehicles inspected at the site.

The storm caught many victims in their vehicles on roads and in underground spaces such as car parks, tunnels and garages where rescue operations are particularly difficult.

On Monday, the family of a missing British couple in their 70s confirmed they had been found dead in their car days after flash flooding hit the region.

There has been anger at a perceived lack of warning and insufficient support from authorities after the floods.

On Sunday, the king and queen of Spain were pelted with mud and other objects by angry protesters during a visit to the town of Paiporta - one of the worst-affected in Valencia.

Objects were also thrown at Prime Minister Pedro Sánchez, who was quickly evacuated.

The Civil Guard has opened an investigation into the chaotic scenes, Interior Minister Fernando Grande-Marlaska told public broadcaster TVE.

He blamed "marginal groups" for instigating the violence where mud spattered the monarchs' face and clothes.

Local authorities in Valencia have extended travel restrictions for another two days to facilitate the work of the emergency services, cancelled school classes and urged people to work from home.

In Catalonia, train services have been suspended due to adverse weather conditions, while footage shared online appears to show vehicles submerged in floodwater on roads. — BBC
