MADRID (AP) — Authorities said 160 would-be migrants tried to break into a fenced-off Spanish enclave on the north African coast Monday, and Spain’s foreign minister worried more may head to Spanish islands near Morocco.

Officials said the migrants tried to breach two sections of the fence between Morocco and the Spanish enclave of Melilla early in the morning, with about 10 succeeding in entering Spanish territory.

A similar storming was thwarted Sunday, but 70 other illegal migrants managed to reach the uninhabited Spanish island of Isla de Tierra.
