Cadiz, Spain - At least four Moroccan would-be immigrants have died while attempting to cross the sea to Spain, officials said Monday.

The bodies of two men and two women were found on Monday on a shore near their wooden boat, which had hit rocks when landing near Barbate on the south-western coast.

Another migrant, a young man, was found seriously injured. Rescuers were looking for more possible victims.

Fifty-six African undocumented immigrants have drowned or died of exposure or other causes while trying to reach Spain so far this year, according to official figures. (dpa)
