On Monday, the International Organisation for Migration (IOM) announced that at least 11,891 illegal migrants were intercepted in the Mediterranean and returned to Libya this year.
It added that 811 women, and 711 children have been intercepted this year. An estimated 316 migrants have died, with a further 417 others remaining lost at sea.
In a tweet, the IOM said that a body washed up on Libyan shores during the period of 22-28 December.
Thousands of migrants remain detained in overcrowded detention centres, despite repeated international calls to close these centres.
The United Nations High Commissioner for Refugees (UNHCR) reiterated that Libya is not a safe port for migrants, and that they must not be returned there.
Libya has become the preferred point of departure for thousands of migrants wishing to cross the Mediterranean to reach Europe.
