An Irish nurse helping migrants on the rescue ship the Aquarius says 'vulnerable people should not be used as pawns in a political game'.
The ship was turned away from Italy and Malta last week, before finally reaching sanctuary in Spain.
Passengers on board included unaccompanied children, pregnant mothers and torture victims.
Nurse Aoife Ní Mhurchú helped to care for hundreds of refugees on board. She says it was a reckless decision to turn them away.
"It was an anxious time for the people on board because the ship was actually stopped halfway between Malta and Italy [for] 24 hours," she said.
Ms Ní Mhurchú says politics was put before the lives of these people, some of whom were very ill.
"The majority of these were chemical burns which required wound care, regular analgesia throughout.
"Then with the deteriorating weather conditions, it was just really challenging because we had to move everybody inside the ship.
