Putin heads to Turkey amid differences over Syria
Russian President Vladimir Putin is heading to Turkey for a one-day trip that is likely to be overshadowed by the two countries' differences over Syria.


The visit to Istanbul also is expected to address concerns over the state of Putin's health. It is Putin's first trip in two months, and the unusual break in his travel schedule has fed speculation that the 60-year-old Russian leader is suffering from serious back trouble or an illness. His spokesman has attributed Putin's discomfort to a pulled muscle. (AP)
