Travellers should exercise increased caution in Spain due to the ongoing threat of terrorism and civil unrest. Terrorist groups continue plotting possible attacks with little or no warning, potentially targeting tourist locations, transportation hubs, hotels, restaurants, and major events. Demonstrations are common and may occur in response to political or economic issues. Additionally, high-speed rail services between Madrid and southern Spain remain severely disrupted following a recent train collision, though most services have resumed except routes to Malaga and Algeciras.
