The head of Russia's space agency say an explosion which brought down a rocket just after launch may have been malicious.
One soldier died and a multi-million pound scientific satellite was lost during the incident earlier this month.
Yuri Koptev said the explosion was caused by an unidentified object in the fuel line.
He said investigators are considering "malicious intent" among other possibilities.
The Soyuz-U rocket blew up within seconds of liftoff October 15 from the northern Plesetsk launch pad.
