German leaders raised the possibility that a fiery cargo plane crash in Lithuania on Monday was the result of sabotage or hybrid warfare.

German officials on Tuesday started to question the crash of a DHL-chartered cargo plane in Vilnius in Lithuania the day before as an act of sabotage.

A team of Lithuanian investigators recovered the black boxes from Monday's deadly cargo plane crash, as they began their probe into what caused the aircraft to go down and worked to clear the crash site.
