We're pausing our live coverage That's it for our live coverage of the blackouts in Spain and Portugal for the time being. The cause of the outage is still unknown, with conflicting reports so far on the likely trigger. Spain's national grid appeared to rule out a cyber attack in an initial assessment, but a Spanish judge has since ordered an investigation - while stressing that "cyber terrorism" cannot yet be discounted for certain. Portugal's prime minister has also called for an independent investigation into what happened this afternoon. Watch our reporting about the uncertain cause in the clip below. The good news is that Spanish and Portuguese authorities have said that most power has been restored. We even spoke to a tourist in Madrid earlier who flew to Spain from the Netherlands without any delays this morning (see our 13.21 post). Finding the whole story overwhelming? Watch a recap of what happened below. Remember to keep watching and following Sky News for the latest updates from around the world, including on Donald Trump's first 100 days and the war in Ukraine.
