Nerve agent victim Charlie Rowley has been released from hospital after three weeks of treatment since being poisoned, U.K. officials said Friday.

Former Russian spy Sergei Skripal has been discharged from a British hospital, more than two months after he was poisoned with a nerve agent and left fighting for his life, health officials said Friday.

As Western countries continue to criticize Russian involvement in the poisoning of a former double agent, Russia is launching a campaign to get its citizens studying in 'unfriendly' countries to return.
