adding that at least 34 others died during the crossing. The influx comes after Spain's Supreme Court ruled that migrants stopped at sea while trying to reach Ceuta or Melilla, another Spanish exclave, cannot be summarily returned to Morocco. Prime Minister Pedro Sánchez described the situation as an "attack" and said all illegal migrants would be returned to Morocco "as soon as possible". Several European leaders have expressed concern, some promising to tighten border controls. More than 25,000 have returned to Morocco voluntarily so far, officials said. UK Prime Minister Andy Burnham and the French president offered to help Spain. Ceuta, on Morocco's northern coast, is separated from mainland Spain by the Strait of Gibraltar and has long been a focal point for migrants attempting to reach Europe. Local officials had appealed to Madrid for help after a recent rise in attempted crossings, but there were chaotic scenes on Thursday as border controls apparently broke down. (BBC)
