New York: Wall Street stocks Friday finished mostly lower followed a cautious appraisal of the US jobs market by Fed Chair Janet Yellen and a sharpening of tensions over Ukraine.
At the closing bell, the Dow Jones Industrial Average stood at 17,000.80, down 38.69 points (0.23 percent).
The broad-based S&P 500 shed 4.02 (0.20 percent) to 1,988.35 while the tech-rich Nasdaq Composite Index gained 6.45 (0.14 percent) to 4,358.55.
Yellen told a gathering of central bankers in Jackson Hole, Wyoming, that while some economic data has improved, there still remains "considerable uncertainty about the level of employment."
The United States called on Russia to "immediately" withdraw a convoy of vehicles from Ukraine and warned of further international sanctions if Moscow did not respect Kiev`s sovereignty.
Russia has said the trucks are on a humanitarian mission, but Kiev had not authorized their entry and said the move was an invasion.
