Prime Minister Pedro Sanchez announced on Saturday that Spain would send 10,000 additional troops and police officers to the eastern Valencia region.
The region has been devastated by unprecedented floods that have claimed 211 lives.
Just over three days after cities and infrastructure were destroyed by muddy water floods, there was little chance of finding survivors in the biggest disaster to strike the European nation in decades.
In the eastern Valencia region, where hundreds of security and rescue services workers were desperately cleaning muck and debris in search of remains, nearly all of the dead have been reported.
In a televised speech, Sanchez declared that the flood was the second-deadliest in Europe this century and added a significant number of security personnel to assist with relief efforts.
The government has granted the Valencia region leader’s request for an additional 5,000 troops and notified him of a further deployment of 5,000 civil guards and police officers.
He stated that Spain was deploying the greatest number of soldiers and security force members in peacetime.
It is crucial to restore order and provide help to devastated towns and villages, some of which have been without power, food, or water for days.
Some affected individuals have complained that the reaction to the crisis is too delayed.
Authorities have faced criticism for the effectiveness of warning systems prior to the floods.
