Under siege, Syrians wait, starve.BEIRUT — Fighting in Syria killed nearly 1,900 people, including at least 430 civilians, during the week of U.N.-hosted peace talks in Switzerland, activists said Friday. The death toll indicates that violence barely paused as the warring parties met but struck uncompromising stances, failing to reach any agreements that could help resolve the conflict.The figures were reported by the Britain-based Syrian Observatory for Human Rights. Its director, Rami Abdurrahman, said the week’s bloody toll was about average at this point in the three-year conflict.The number included at least 430 civilians, killed by bombs, snipers, missiles, and other causes. The rest were rebels and forces loyal to President Bashar Assad. The Observatory obtains its information from activists on the ground, and also keeps a running total.The conference didn’t produce any tangible results, although connections made in Switzerland are likely to develop into prolonged negotiations to try to resolve the war.The conflict began as largely peaceful protests against Assad in March 2011, but became an increasingly sectarian civil war that has killed more than 130,000 people. It has forcibly displaced one-third of the entire prewar population of 23 million, including over 2 million who have flooded into neighboring countries. Tens of thousands more are blockaded in rebel-held areas, where Assad loyalists prevent food and aid from entering.
