British holidaymakers planning to jet off to Spain have been warned that many of the beautiful islands are turning into "cemeteries".

It comes after at least five bodies were spottedfloating in the Balearic Islands, with their hands and feet shackled. Now, tourists have been told that the gruesome finds could become more common in Majorca, Ibiza, Menorca and Formentera.

Over the past six weeks, six corpses were found washed up in the sand in front of shocked locals. On Saturday, a human foot was spotted on a beach in Can Pastilla, Majorca, making it the tenth harrowing discovery at the destination this year.

The day before, parts of a female body were found decayed and drifting close to Can Pastilla. The Civil Guard believe that the human remains belong to migrants who have tried to reach Spain via a dangerous crossing from Algeria.

The sixth body, which appeared to be a male, was found this week on the beach of Cala Mesquida in Capdepera. The body is said to have come from a vessel carrying 27 Somali nationals that vanished after departing Algeria on February 2. Another decomposed body was located on a beach in Playa de Palma, the same day.

With hundreds of migrants having already arrived in boats across Spain in winter, Brits have been told the situation could escalate in the summer due to calmer waters. Officials compared the islands to a "graveyard" as they commented on the increasing number of bodies. "The Balearic Islands are a cemetery," reports Spanish newspaper, Diario de Mallorca.

It has been reported that locals have urged tourism bosses to address the situation by displaying images of corpses instead of the picturesque beaches. Stunning locations, including Can Pastilla (Palma), Cala Deia, Llevant beach in Formentera and Son Moli in Cala Rajada, have been the sites of several body recoveries in the last two weeks.
