A person has died after jumping over the border fence separating Morocco from Spain's autonomous enclave Melilla during a mass border breach involving around 300 mainly sub-Saharan migrants, local authorities said Sunday.

Spain's government delegation in Melilla said the deceased was one of several migrants who were attended to by police and Red Cross workers after sustaining injuries in their attempt to rush the border.

"Today 200 people made the irregular crossing into Melilla and one has died," Spain's Prime Minister Pedro Sánchez said on Twitter. "The government will always support a coordinated and European solution to the migration challenge," he added.

A Spanish government representative in the region said an autopsy would be carried out on the deceased, although initial signs suggested the person suffered a cardiac arrest.

Officials said a total of 25 people were injured during the border breach, including 19 migrants and six police officers.

Of the 300 migrants who stormed the border, which is lined with around 11 kilometers (6.8 miles) of parallel fencing reaching up to 6 meters (almost 20 feet) high and topped with razor wire, some 200 made it into the city of Melilla.
