WASHINGTON - The United States is taking steps to try to avoid a conflict between Turkey and US-backed Kurdish forces in Syria, the top US commander overseeing American troops in the Middle East said on Thursday, acknowledging the risk of a clash existed. Asked by influential Senator John McCain whether he shared the view about the risk of a conflict between the two US allies, Army General Joseph Votel said: 'I do, Mr. Chairman. And to that end, we are trying to take actions to prevent that from occurring.'
