Migrants made an attempt to cross a seven-meter high fence separating Morocco from Spain, at 6:35 a.m. They threw stones, sticks, Molotov cocktails, feces and hashish at law enforcement representatives and used sprays as flamethrowers. The migrants tried to cut the barbed wire on the fence with scissors and hammers.

Once they entered Spanish territory, they threw stones at cars of the Civil Guard.
Earlier, 592 migrants who managed to cross the border had applied with the International Organization for Migration; 132 of them were injured, and 11 migrants were taken to hospitals.
Since the beginning of the year, through the enclaves of Melilla and Ceuta, according to the International Organization for Migration, 3,125 migrants crossed the Spanish border, not including those who crossed the border on Thursday.
Ceuta is a Spanish autonomous city in North Africa, sharing a four-mile-long border with Morocco. Rabat has repeatedly called on Madrid to transfer the sovereignty over Ceuta and the neighboring city of Melilla. The residents of the city insist the territories should remain part of Spain.
