Lithuania has found no evidence of terrorism or sabotage so far in its investigation of a DHL cargo plane crash near Vilnius airport, prosecutors said on Tuesday.

The aircraft's black boxes containing flight data and voice recorders have been found and investigators are preparing to examine the material, the government later said in a statement.

The plane crashed as it came in to land in the early hours of Monday, killing one person on board in what Germany's foreign minister later said might have been an accident or a hybrid attack in "volatile times".

The Lithuanian General Prosecutor's office is leading one of two official probes into the crash of the Boeing 737-400, which was operated by Spanish airline Swiftair on behalf of the German logistics group.

"Our initial information does not indicate that we need to be investigating more serious actions," Prosecutor Arturas Urbelis said in a statement, adding that the probe was still under way.

"We might find signs of activities of other kinds as we investigate," Urbelis said.
