The US believes that the Malaysia Airlines passenger plane, which crashed Thursday in Ukraine, was downed by a surface-to-air missile.
An anonymous official said that it is still unclear where the missile was launched from, the Voice of America reported.
And according to the Reuters’ source, official Washington has serious suspicions that the missile was launched by the pro-Russian activists backed by official Moscow.
Earlier, however, the Ukrainian forces and the pro-Russian activists had blamed one another for the tragedy.
