Millions of people in Spain, Portugal and parts of southern France lost power on Monday following a “severe disruption” in the European electrical system, Spanish Prime Minister Pedro Sanchez said.

The cause of the disruption is still unknown, Sanchez said in remarks Monday evening local time.

The Spanish government said it called an emergency crisis meeting to fix the situation as soon as possible.

Red Eléctrica, the corporation that operates the national electricity grid in Spain, said it is working on restoring power to mainland Spain and Portugal. In an update Monday night local time, they said nearly half of the substations have power again. Earlier in the afternoon, they said electricity should be fully restored within six to 10 hours.

Authorities, meanwhile, asked people to stay at home, while emergency generators were also being put in place.

Airports in the country were not closed, but they are seeing massive delays.
