NEW YORK, Aug 22 (Reuters) - U.S. stock index futures were slightly lower on Friday, after the latest flare of tensions between Ukraine and Russia and ahead of a speech by Federal Reserve Chair Janet Yellen.

* After holding near the unchanged mark, futures lost ground after Ukrainian authorities said 90 trucks from a Russian aid convoy had crossed into Ukraine without permission and Ukraine's state security chief said the move amounted to a "direct invasion" by Russia.

* Market participants will closely monitor a speech Yellen is due to make at a policymakers' meeting in Jackson Hole, Wyoming, for insights into how soon interest rates may be raised. European Central Bank President Mario Draghi is also expected to speak.

* The S&P 500 notched its fourth straight gain on Thursday and rallied to its most recent record closing high of 1,992.37, buoyed by a flurry of positive economic data. The benchmark index is up 1.9 percent for the week, on track for its best week in four months.

* S&P 500 e-mini futures were down 2.5 points and fair value - a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract - indicated a slightly lower open. Dow Jones industrial average e-mini futures fell 13 points and Nasdaq 100 e-mini futures lost 4.75 points.   Continuación...
