"The conclusion, voiced by the JIT during a press conference on May 24, that the Buk air defense system, which launched a missile at the aircraft, arrived in Ukraine from Russia and belonged to the 53nd Air Defense Brigade stationed in Kursk, causes us regret," the ministry said in a statement.
According to the statement, the Dutch-led Joint Investigation Team (JIT) has ignored a significant amount of information, including radar monitoring data that cannot be manipulated.
"In these circumstances, we have legitimate questions about the true reason for the JIT decision to announce the preliminary conclusions of the probe. In out opinion, all this only confirms our earlier concerns about the biased and one-sided approach to the ongoing investigation," the statement said.
"Nevertheless, we will continue to assist the [international] investigation so that the truth about the MN17 catastrophe is established, and the real culprits of the tragedy receive fair punishment," the ministry added.
Earlier in the day, head of the Dutch National Police's Central Crime Investigation department Wilbert Paulissen said that the missile, which downed Malaysia Airlines Flight MH17 in eastern Ukraine in 2014, was launched by the Buk TELAR belonging to the Russian Armed Forces.
Back in 2016, the Dutch-led Joint Investigation Team already presented the initial results of the criminal investigation into the crash, claiming that the airliner was downed by a Buk surface-to-air missile launcher which was delivered from the "territory of the Russian Federation to Ukraine."
Malaysian Airlines' Boeing 777 crashed in eastern Ukraine in July 2014 during its flight to Kuala Lumpur from Amsterdam, while all 298 passengers and crew members on board were killed.
