U.N.: Syria has agreed to observer team People bury the bodies of men activists say were killed by the Syrian government army, in Taftanaz village, east of Idlib, Syria April 5, 2012. PARIS, April 19 (UPI) -- Syria has agreed to accept a 30-person team of U.N. observers, Special Envoy Kofi Annan said Thursday. Annan, who is an envoy for both the United Nations and the Arab League on Syria, is in talks with the government and opposition representatives, the United Nations said. "The hard part lies ahead, a truly Syrian-led and -owned political dialogue to address the legitimate concerns and aspirations of the Syrian people," the spokesperson added. The first group of unarmed observers arrived in Syria earlier this week. Whether the observer mission will have any effect is another question. U.N. Secretary-General Ban Ki-moon told the Security Council in a letter that Syria has failed to implement nearly every aspect of a six-point peace plan since the April 12 cease-fire, The New York Times reported Thursday. The United Nations had been negotiating for a 300-member mission. In Paris, U.S. Secretary of State Hillary Clinton, along with foreign ministers from the Middle East and elsewhere, gathered Thursday for a "Friends of Syria" discussion of the peace plan and ways to pressure Damascus. Before the meeting, Clinton said Syrian regime backers must justify how they can let the bloodshed go on. "The burden has shifted," Clinton told reporters in Brussels before flying to Paris for the meeting to boost pressure on Syrian President Bashar Assad's regime. The barrage of bullets -- in the suburban city of Arbeen near Damascus -- sent the observers' vehicles racing away, sirens blaring, and protesters scattering, running for cover, the amateur videos posted online showed. The Assad regime says it has a right to respond to "terrorist" attacks, despite agreeing to the six-point peace plan brokered by U.N.-Arab League envoy Kofi Annan.
