The Murmansk court will on Monday morning hear a petition for the revocation of Saarela’s pre-trial detention, Greenpeace spokesperson Juha Aromaa confirmed to Yle.

Finnish Consul Martti Ruokokoski will be present in the courtroom.

On Friday the court heard four activists' petitions, rejecting all of their appeals.

“Unfortunately, hopes are not very high. Previous petitions have all been rejected almost in the same terms,” Aromaa said. “However, all possible petitions will be made.”

According to Aromaa, the Greenpeace support team is on hand in Murmansk.

On September 30 Russia arrested the activists after they tried to climb energy giant Gazprom’s Pechora oil rig.

The Murmansk court ordered their two-month pre-trial detention. The activists stand accused of piracy, which can incur many years of imprisonment.
