¿Se celebrarán concentraciones públicas convocadas por la FEMP en apoyo a Ceuta en al menos tres capitales de provincia españolas el 2 de septiembre?

Por qué: Multiple independent, reputable news outlets in the supplied evidence report that the Federación Española de Municipios y Provincias (FEMP) called nationwide concentrations for 2 September 2026 and that demonstrators physically assembled in multiple provincial capitals that day. Reuters (2026-09-02) states the FEMP called the Spain-wide protests and that demonstrations “also took place ... including Madrid, Barcelona and Bilbao.” DW reports the protests were officially organized by the FEMP with large turnouts in Madrid, Barcelona and other provincial capitals. Al Jazeera and AP likewise report thousands rallying across Spain (around 50,000 in Madrid alone). These independent sources corroborate the same dated outcome (FEMP-called concentrations with assembled demonstrators in at least three distinct provincial capitals on 2026-09-02), so the correct settlement is YES.
