Malta's armed forces have taken control of a tanker that was hijacked by migrants it had rescued off Libya.
It said a special operations team escorted the vessel to Malta where it was "handed over to the police for further investigations".
The Palau-flagged tanker Elhiblu I picked up the migrants on Tuesday evening in waters where Libyan coastguards are responsible, and then headed back to Tripoli.

The tanker was about 30 nautical miles from Malta when the Armed Forces of Malta (AFM) established communications with the captain.
"The captain repeatedly stated that he was not in control of the vessel and that he and his crew were being forced and threatened by a number of migrants to proceed to Malta," the AFM said in a statement.
"AFM Patrol Vessel P21 stopped the tanker from entering the Maltese territorial waters.
"An AFM Special Operations Unit team was dispatched to board and secure the vessel in order to hand over control of the ship to the captain."
It said the team was backed up by several naval vessels and a helicopter.
