Mediterranean Drownings: The High Commissioner’s Comments
15 April 2015
The High Commissioner for Refugees António Guterres expressed shock at news from the Mediterranean that hundreds of people were missing after their boat sank and called anew for urgent action to prevent such tragedies in the future.
THE UN refugee agency has said once again that not enough is being done to save the lives of the tens of thousands of migrants who are being driven by hunger to try to cross the Mediterranean from Libya to Europe: here.
Four hundred migrants fleeing Libya have reportedly drowned after their boat capsized in the Mediterranean last weekend. A spokesman for the International Organisation for Migration in Italy told Agence France-Presse that survivors reported there were up to 550 people on board when the ship sank. Around a dozen bodies have been recovered so far: here.
