"I've decided to enter the port of Lampedusa," Captain Carola Rackete explaines in a video tweeted by the Sea Watch 3 account.
"I know this is risky, but the 42 shipwrecked on board are exhausted. I will bring them to safety."
In a video post late afternoon, Ms Rackete added: "And now they are waiting for further instructions from their superiors. I really hope they will take the rescuees off the ship."
