A sailing yacht has sunk in Moroccan waters in the Strait of Gibraltar after being rammed by an unknown number of orcas, Spain's maritime rescue services said.
Two people onboard the vessel, Alboran Cognac, were rescued by a passing oil tanker, after the incident at 0900 local time (0800 BST) on Sunday.
It is the latest in a series of orca rammings of vessels around the Strait of Gibraltar over the past four years.
Scientists are unsure about the exact causes of the behaviour, but believe the highly intelligent mammals could be displaying "copycat" or "playful" behaviour.
