Prime Minister Pedro Sanchez on Monday accused Russia and Israel of spreading disinformation about Spain’s migration policy that helped trigger last month’s migrant surge into Ceuta, but said no evidence linked Morocco.

Over 72,000 migrants irregularly crossed ​from ⁠Morocco into the tiny Spanish territory between July 30 and 31 in an unprecedented surge at one of the EU's only two land borders with Africa, prompting alarm across the bloc. At least 100 people died in the attempt, according to Ceuta's local authorities.

Spanish opposition parties and some human rights groups have accused Rabat of deliberately allowing the mass crossing, an accusation Morocco has denied.

"When people talk and speculate about the participation of Moroccan authorities, I deny this outright," Sanchez told radio station SER.

Videos on Instagram, TikTok and other social media spread misleading claims that migrants ⁠reaching ⁠Ceuta by sea could remain in Spain, encouraging thousands to attempt the crossing, Spanish authorities have said.
