The BBC's Colombo correspondent Charles Haviland travels around Sri Lanka, the island nation which saw an epic battle to defeat the feared Tamil Tiger militants seven months ago. The conflict may be over but many say Sri Lanka remains on a war footing - an island full of restricted areas, where refugees are on the move and newspaper editors still face death threats. Crossing Continents tells the untold story of a fragile society, as people from the Sinhalese majority and the Tamil minority return to bombed-out villages and towns. Charles Haviland explores Sri Lanka and asks if the government and army that won the war can now win the peace.
