BRUSSELS (AFP) - Serbia and Kosovo scored a key breakthrough Saturday in efforts to put tension at rest, agreeing several deals to ease the headaches caused by Belgrade's refusal to recognise Pristina's independence. Negotiators from both sides have been meeting in EU-brokered talks since March in a bid to solve the daily problems for ordinary people stemming from Kosovo's declaration of independence three years ago. Meeting for a fifth round, negotiators agreed Saturday to ease free movement of people across the contentious border, an EU source said.
