The migrant rescue ship Ocean Viking has rescued 203 people, including 67 minors, in recent days, its owner SOS Mediterranee said Sunday.
The migrants came from Egypt, Gambia, Libya, South Sudan, Syria and Tunisia, the non-governmental organization said in comments posted on Twitter.
They were rescued in four separate operations since Thursday.
They had used up reserves of food and water and four people “had to be evacuated on stretchers”, the group added.
Since the start of the year, 886 migrants have died in the Mediterranean while trying to reach Europe, according to figures compiled by the International Organisation for Migration.
SOS Mediterranee says it has rescued more than 30,000 people since February 2016.
