The LE Eithne has successfully located and rescued a small boating craft with 113 people on board that was in distress 40km north of Tripoli, Libya.
The rescue took place at approximately 5pm on Saturday evening.
The rubber inflatable craft was located within the area being patrolled by the Irish Naval Service team and is the fifth successful operation the team has undertaken since its departure from Cork three weeks ago.
The ship has already saved a total of 756 migrants since commencing the operation in the Mediterranean.
The LE Eithne has since resumed patrol in the designated area.
It departed from the Naval Service Headquarters in Haulbowline, Cork to assist the Italian Authorities in the humanitarian search and rescue operations in the Mediterranean on May 16.
The operation is ongoing.
