Investigators said Tuesday that suspected Russian missile parts were found near where Malaysia Airlines Flight MH17 crashed in eastern Ukraine last year.

“The parts are of particular interest to the criminal investigation as they can possibly provide more information about who was involved in the crash of MH17,” the Joint Investigation Team said in a statement with the Dutch Safety Board.

The development marks the first time investigators confirmed potential physical evidence related to the July 17, 2014, crash that killed all 298 people on board.

Investigators nevertheless stopped short of linking the crash of MH17 to the the new find, which the team and board said contains components possibly from a Russian-made Buk surface-to-air missile system.
