The US State Department has called for "moderation from all those involved" in the protests around Catalonia following the announcement of the sentences in the Catalan trial. A spokesperson has told Spanish news agency EFE they also encourage everyone to act "in a manner consistent" with Spanish law.

The demonstrations are being closely followed by diplomats of different countries. The US embassy to Spain and Andorra has published regular Demonstration and Safety Alerts to keep their citizens in the area informed and give them advice. The UK's Foreign Office, for its part, today updated its travel advice for Spain to included the note: "There have been large gatherings of people in Barcelona and other areas of the Catalonia region in relation to the political developments there. Further gatherings and demonstrations are likely to take place. They may occur with little or no warning and even demonstrations intended to be peaceful can escalate and turn confrontational. You should exercise caution if you’re in the vicinity. Demonstrations may also cause some disruption and delays to transport services."

Donald Trump's government has also said it would prefer a "united Spain". It made similar comments in October 2017, at the height of the events that led to yesterday's verdicts. US State Department spokesperson Heather Nauert then released a brief statement saying that "Catalonia is an integral part of Spain" and that they support the measures taken by the Spanish executive to maintain a "strong and united" Spain.
