(CNN)Migrants rescued by a boat funded by the British street artist Banksy have been evacuated onto Sea-Watch 4, another vessel that rescues people stranded in the Mediterranean Sea.
Migrants on a Banksy-funded rescue boat have been transferred to another vessel after request for 'immediate assistance'
A Saturday evening post on the vessel's Twitter account said it had "just transferred all remaining guests onto #SeaWatch4, who now have about 350 people on board."
"It's not over," the tweet said. "We demand a Place of Safety for all survivors, now."
The transfer took place after the "Louise Michel," a former French naval ship purchased by Banksy, took 219 migrants onboard and requested "immediate assistance."
Sea-Watch International confirmed on Twitter that its vessel had received the passengers, adding, "we now have (about) 350 people on board who need to disembark in a safe port as soon as possible."
