Russia formally drops criminal charges for Greenpeace activists arrested during a protest over Arctic oil drilling.

Greenpeace said 29 of the 30 activists are now free to go.

They were given amnesty and are free to leave Russia as soon as they get exit visas.

The last activist's case will be reviewed on Thursday.
