Kiev, Ukraine: Ukrainian forces say one of their fighter jets has been shot down by a Russian missile in combat against Russia-backed separatists in eastern Ukraine. A brief statement posted Saturday on the Facebook page for the so-called operation against separatists said the Su-25 was hit on Friday, and that the pilot ejected and was uninjured. The statement said the plane was hit by a missile from a Russian launcher, but did not give more detail.
