All major mobile networks went down in Spain on Tuesday, just four weeks after the country was hit by a national power outage.

Movistar, Orange, Vodafone, Digimobil and O2 were all reported to have been affected.

Issues with network connectivity began around 5am this morning, according to Downdetector.

Landlines were described as 'silent' and the emergency number 112 not working in several parts of the country, Il Corriere reports.

Emergency phone lines have been restored in Aragon, near the border with France, but problems remain elsewhere, Metro reports.
