About 30 anti-war activists protested on Monday in front of Pablo Picasso's historic Guernica painting about the horrors of war at the Reina Sofia Museum in Madrid, hours before the start on Tuesday of a NATO summit in the Spanish capital.
The protesters blame the military alliance for stoking the war in Ukraine and argue that "security is not achieved with more weapons", protest organizers Extinction Rebellion and Fridays For Future said in a joint statement.
