Spain's prime minister has blamed trafficking gangs after about 60,000 migrants crossed into the Spanish North African enclave of Ceuta from Morocco. The influx comes after Spain's Supreme Court ruled that migrants stopped at sea while trying to reach Ceuta or Melilla, another Spanish enclave, cannot be summarily returned to Morocco. As of Friday evening, more than 48,000 people had voluntarily returned to Morocco, Spanish officials said. During the summer months there is often a big push to reach Ceuta, typically organised over social media. Coveted by Morocco, Ceuta and another Spanish enclave Melilla have long been a flashpoint in diplomatic relations between the two countries.
