The prime minister of Spain is promising to release all files related to the invasion of Ceuta by illegal immigrants, as thousands rally across the country in protest of how the situation has been handled.

Prime Minister Pedro Sanchez addressed the situation on Thursday in the Spanish parliament’s lower house, the Congress of Deputies. Reacting to accusations that the Moroccan government allowed the invasion to take place, as well as speculation that the Spanish authorities failed to react effectively to the situation, the premier promised to publish a comprehensive document examining the timeline of events.
