Over 80 migrants are reportedly missing at sea on Thursday following a shipwreck on Wednesday off the coast of Zarzis, Tunisia.

There were only five survivors, according to Alarm Phone, which announced the news on Twitter and attributed it to Tunisian Red Crescent volunteer and activist Chamseddine Marzoug.

Marzoug told ANSA a rubber dinghy that had departed from Libya sunk on Wednesday off the coast of Zarzis and that one of the five survivors, a man from the Ivory Coast, later died in hospital.

Local authorities said the Tunisian Red Cross and the International Organization for Migration (IOM) are working in coordination with Tunisian authorities on search-and-rescue efforts at sea, together with some local fishing boats.
