'Record year' for migrant arrivals to Europe says UN
Several hundred migrants from Africa and the Middle East who were trying to reach Europe are feared to have died over the past few days.
The International Organisation for Migration says up to 500 people trying to reach Italy are believed to have lost their lives when their boat sank near Malta on Thursday.
In a separate incident, the Libyan navy said dozens of African migrants have drowned off the Libyan coast after the vessel they were travelling in sank.
Andrej Mahecic from the UN Refugee Agency told the BBC that the number of migrants was increasing.
