Syrian war wreaks overwhelming damage on cities - U.N.

BEIRUT (Reuters) - Syria's civil war has inflicted such carnage that in some districts of Damascus three quarters of homes have been damaged and more than 90 percent of residents say they need help to survive, according to a U.N. survey released on Wednesday.

Three years of conflict have devastated the country, destroying infrastructure and reducing some neighbourhoods to ruin. But the ongoing violence has meant there have been few detailed studies into the scale of its impact.
