Four Moroccan migrants trying to reach the European Union have drowned in the Atlantic Ocean, officials and relatives said Friday.
Three other migrants were rescued after their vessel sank off the resort of Skheirat, south of the capital Rabat, on Thursday.
"We are in shock. My cousin, who was 29, was among the dead," said a relative of one of those who drowned.
"They were all Moroccan. We had no idea he was going to try to make the voyage."
Officials said the migrants' vessel was believed to have had a capacity of up to 20 people, and a search was continuing for any other survivors.
