Aid group Doctors Without Borders (MSF) said on Tuesday that around 6,000 people are being held in migrant detention centers in Libya, adding they should be evacuated to Europe. Rights groups have documented cases of abuse and torture in the Libyan centers, while a two-month conflict around the capital Tripoli has made the situation worse. "There are no safe places in Libya to take these migrants and refugees in order to remove them from the risk of conflict," Sam Turner, MSF head of mission in Libya said at a press conference in Rome on Tuesday. "This is why we are urgently calling for their humanitarian evacuation".
