Members of illegal armed units have not seized air defense launchers of the Ukrainian Armed Forces in Donetsk, Ukrainian Prosecutor General Vitaliy Yarema said.

"The military told the president after the passenger plane had been shot down [in the Donetsk region] that the terrorists did not possess our Buk and S-300 missile systems. Such had not been seized," the prosecutor general told the Ukrainska Pravda online edition after the Thursday meeting of the Ukrainian National Security and Defense Council.

The Ukrainian Defense Ministry said earlier air defense missile systems of the Ukrainian Armed Forces had not been used in the antiterrorism operation and there were no Ukrainian fighters in the air at the time the Malaysian airline crashed.
