According to the city hall office in Barcelona, the police estimate that 70,000 people participated, while the organizer claims that 300,000 gathered.
Among the demonstrators, there were Palestinian flags and signs with messages such as "Stop the genocide" and "Keep your hands off the flotilla", referring to the Global Sumud Flotilla activist convoy.
How is it possible that we are witnessing a genocide in real-time after what we experienced in the 1940s? Now no one can say that they did not know what was happening, says demonstrator María Jesús Parra to AP.
The Spanish demonstrators' pro-Palestinian stance is in line with Prime Minister Pedro Sánchez's position. Sánchez's government has, among other things, called the destruction and killing in the Gaza Strip a genocide and urged to ban Israelis from sports competitions.
Large protests are also taking place in Rome, Madrid, and Lisbon on Saturday.
