Divers searching for a hijacked An-2 biplane that disappeared more than a week ago with 13 revelers on board came back empty-handed after scouring a reservoir earlier believed to be the crash site.

"What was assumed to be the [crash] site has been searched. The airplane was not found," a source in the Urals security services told RIA-Novosti.

An emergency services source had told Interfax on Wednesday morning that a large patch of oil was discovered on the surface of a reservoir to the north of Serov, the Urals city from which the light aircraft disappeared June 11.

At the time, the source presumed this oil spot was a trace of the missing plane.
