A record 1,500 migrants, mainly from Somalia and other parts of Africa, died trying to reach European shores in 2011 and the deadly odyssey continues from Libya, the United Nations refugee agency (UNHCR) said recently. It said popular uprisings in Tunisia and Libya prompted more people to flee last year, including sub-Saharan migrants working in North Africa, after tighter border measures sharply reduced arrivals in Europe in 2009 and 2010.
