The Russian security service says a group of Greenpeace activists are being held on suspicion of piracy.
The campaigners were detained last Thursday after trying to climb onto an offshore platform as a protest against oil drilling in the Arctic Ocean.
Their boat, the Arctic Sunrise, was seized. The Russian authorities say all those on board will be questioned
