The Greenpeace activists were brought to court in police vans A Russian court is meeting to rule on whether 30 Greenpeace activists should stay in custody pending an inquiry into their actions during an oil protest.Activists were ferried to the courthouse in police vans in Murmansk, a port city north of the Arctic Circle.
Coastguards arrested the activists on suspicion of piracy after two scaled an offshore drilling platform.
Greenpeace says the campaigners, who are from 18 countries, were staging a legal, peaceful protest.
Russian President Vladimir Putin has said the activists are obviously "not pirates" but did not criticise their continued detention.
The charge of piracy carries a prison term of up to 15 years in Russia.
Thursday's proceedings in Murmansk's Lenin district court were broadcast live by TV teams which crowded into the small courtroom.
Greenpeace says that all of the activists have now been questioned in the presence of lawyers. Relatives of some of them told the BBC on Tuesday that they had spoken to them and they were all being well treated.
The BBC's Daniel Sandford: "This is the first time that Greenpeace have found themselves at the criminal end of the piracy law"The drama began a week ago, when two activists successfully climbed on to the side of a platform operated by Gazprom, Russia's state gas monopoly.
They were detained after a short skirmish in inflatable dinghies in which armed Russian FSB officers in balaclavas fired warning shots into the water.
The ship, the Arctic Sunrise, with all its crew was then towed to Murmansk.
Russia views its huge fossil fuel deposits under the Arctic as vital to its economic future, which is why it takes any threat to their exploitation very seriously, the BBC's Daniel Sandford reports from Moscow.
The campaigners on the ship are from Australia, Brazil, Canada, Denmark, France, New Zealand, Russia, the UK and the US, Greenpeace said.
