U.S. stocks closed mixed Friday, due to a lackluster August jobs report and more concerns about Syria. In U.S. economic news, after initially pushing stocks higher on the prospect that the Federal Reserve (Fed) might delay its plans to taper in September, investors quickly shifted their attention to the G20 meeting in St. Petersburg. Russian President Vladimir Putin spooked the markets with comments about his support for Syria. The indexes briefly tumbled after Putin told reporters that Russia would continue arms sales and provide aid to Syria if the nation were attacked. Putin's comments came as U.S. President Obama seeks international and domestic backing for military action against Syria in response to the Syrian's government's alleged use of chemical weapons against its own people last month. The weak August jobs report led some investors to think that the Fed may hold off on plans to start trimming its bond buying program later this month.
