The number of Syrian refugees registered in Lebanon has exceeded one million, in what the UN refugee agency calls a "devastating milestone" for a small country with depleted resources and brewing sectarian tension.<br /><br />Refugees from Syria, half of them children, now equal a quarter of Lebanon's resident population, the United Nations High Commissioner for Refugees said in a statement, warning that most of them live in poverty and depend on aid for survival.<br /><br />Al Jazeera's Rula Amin, reporting from Tripoli in northern Lebanon, said the cost of the Syrian crisis to Lebanon had been estimated at $.2.5bn in 2013 alone, not just from aid and providing services.
