What triggered the mass migrant crossings into Ceuta?

Approximately 60,000 migrants from Morocco have crossed into Ceuta, with dozens of individuals dying during the process. Spain has condemned the 'selfish' responses from some EU countries regarding the situation. In a significant move, Italy has temporarily suspended the Schengen arrangement with Spain, while Prime Minister Giorgia Meloni characterised the scenes witnessed in Ceuta as 'shocking'. These events have created diplomatic tension between Spain and other European Union member states over the migrant crisis.
