A Malaysian airliner shot down in eastern Ukraine was hit by a Russian-made Buk missile launched from a village held by rebels fighting Ukrainian government forces, international prosecutors said Wednesday.<br />The findings challenge Moscow's suggestion that Malaysia Airlines flight 17 was brought down by the Ukrainian military.<br />All 298 people on board, most of them Dutch citizens, were killed.<br />It was not clear whether an order had been given for fighters to launch the missile or whether they had acted independently, the prosecutors said.<br />First-hand radar data identified all flying objects which could have been launched or were in the air over the territory controlled by rebels at that moment.
