Obama urges Congress not to turn 'a blind eye' to Syria According to a Washington Post survey, 224 of the current 433 House members were either "no" or "leaning no" on military action as of Friday. A large number, 184, were undecided, with just 25 backing a strike. The Senate and the House are expected to vote on the issue within the next two weeks. Amid deep global divisions over the Syria crisis - with Assad ally Russia strongly arguing against any intervention - US Secretary of State John Kerry has travelled to Europe to bolster support for military action. Mr Kerry went into informal talks with the EU's 28 foreign ministers in Lithuania, which currently holds the EU's rotating chair, with the bloc itself sharply split on Syria and most nations highly reticent over military action. In France, so far the sole EU nation determined to join a US-led strike, the latest public opinion poll showed 68 percent of people opposed to military action in war-torn Syria, an increase of nine percentage points since late August. In Vilnius, Mr Kerry pressed the case for punitive action against Syria over last month's deadly gas attack, which the United States says was carried out by Assad's regime - a claim denied by Moscow. A State Department official said Mr Kerry expected "a fairly detailed discussion about our thinking" but noted "that there are divisions within the EU about what is the exact sequencing of the need for an international response." As talks between Mr Kerry and his EU counterparts dragged well beyond schedule, also touching on the Middle East peace process, EU diplomats reported intense backroom negotiations taking place to seek a consensus on Syria. France and Denmark are supportive of a US-led strike but Germany, Sweden and others were refusing to endorse action without a UN mandate or a debate within a UN framework. The talks take place after Mr Obama and his Russian counterpart Vladimir Putin failed to bridge their differences at the G20 summit of top global powers. Just over half of the G20 states signed up to a statement calling for a "strong" response to last month's alleged chemical attack, with Britain, France, Italy and Spain the only EU countries of the 11 nations that signed. The statement called for a response that would "send a clear message that this kind of atrocity can never be repeated." It did not specify military action and European diplomats said the language remained vague. Mr Putin has warned it would be "outside the law" to attack without the UN's blessing. Many European nations too are urging a postponement of any action until the release of a much-anticipated report by United Nations inspectors on the deadly August 21 attacks that left hundreds dead. At the G20, French President Francois Hollande vowed to wait for the report before joining any military action, a decision welcomed by Germany. In Vilnius, German Foreign Minister Guido Westerwelle had urged the UN on Friday to publish its report "as quickly as possible" to help Europe's divided leaders determine a response. A US State Department official in Vilnius told AFP that while Mr Kerry had heard those requests, "he also made clear that the United States has not made the decision to wait (for the UN report) ." Russia and China - both veto-wielding permanent members of the UN Security Council - have on three occasions voted down resolutions that would have put pressure on Assad. Washington meanwhile is evacuating non-essential embassy staff from Beirut and urging Americans to avoid all travel to Lebanon and southern Turkey. Later Saturday, Mr Kerry is due to fly to Paris for talks with French officials. He will meet Arab League leaders there on Sunday to update them on Syria and on progress in the Israeli-Palestinian peace process. He will travel on to London for talks late Sunday with Palestinian president Mahmud Abbas, before flying home Monday. Pope Francis has appealed for a peaceful solution to the crisis, calling on the world to unite on Saturday in a day of fasting and prayer for Syria. He will lead the way with a five-hour vigil in St Peter's Square.
