The LÉ James Joyce rescued more than 400 migrants from the Mediterranean yesterday in three separate operations.
Twenty-five people were rescued from a wooden vessel, 130 were rescued from a rubber craft and a further 278 were rescued from a second rubber vessel.
Another 163 migrants were then transferred to the LÉ James Joyce (pictured below) from an NGO vessel.
Commandant Pat O'Connor said: "The next operation is to make sure all these migrants receive the treatment and care they require. They are then brought to the port of safety and handed over to the Italian authorities.
"The LÉ James Joyce will refuel, resupply and then move back out to the area of operations.
