The UK foreign office deletes a tweet claiming British experts had found the nerve agent used in the Skripal poisoning case was produced in Russia. The EU rejects Russia's proposal for a joint investigation into the poisoning of the former spy and his daughter claiming that Moscow refused to co-operate with London. Russia, Turkey and Iran agree on a joint-effort to rebuild Syria - but warned about militant attempts to sabotage the peace process with chemical attacks. And, an American photojournalist who was once held by Al-Qaeda in Syria says he was betrayed by the FBI - claiming he was used by agents to track the terrorists instead of trying to rescue him.
