On May 23, Basque regional police detained four individuals at Bilbao airport following the arrival of six activists from the Global Sumud Flotilla on a flight from Turkey. Reports confirm scuffles occurred after officers prevented a relative from approaching the arrivals, with arrests for disobedience, resisting arrest, and assault; an internal investigation into officer conduct was opened. The incident follows the interception of hundreds of flotilla participants, including 44 Spanish nationals, by Israeli forces at sea on May 18.
