Missile that hit Poland appears to have been fired by a Ukrainian air defense system that malfunctioned

Intel experts in the U.S. believe the missile that killed two people on a farm in Poland near the Ukrainian border came from a Ukrainian air defense system that malfunctioned. The system is intended to defend against the ongoing Russian missile barrage. Now, top Pentagon officials are hoping to ease tensions after early suggestions that Russia had fired the missile into Poland, which would require a NATO response.
