A rescue ship with more than 200 migrants aboard is struggling to find a port that will allow it to dock.
The vessel of German NGO Sea-Watch has so far been denied access to Malta.
“This charade has to end!” Sea-Watch said, claiming that the migrants are in bad health.
A teenage boy with “extensive fuel burns” was rescued by Italy’s Coast Guard on Wednesday and transferred to a hospital, but the others are still waiting to dock.
The migrants were saved during several operations launched in the Mediterranean earlier this week.
Eighty-nine of them were first rescued by the Louise Michel, a pink vessel painted and sponsored by street-artist Banksy, before being transferred aboard the Sea-Watch 4 later.
