Novichok II: What's behind new nerve agent poisoning in England?
Some are calling it Novichok II. Just a few kilometres from where a former Russian spy and his daughter were poisoned four months ago, a local couple are in critical condition, victims of the same military grade nerve agent. Moscow again denies unleashing Novichok and offers to help in the probe - help once again rejected by London. Is this a new attack, or were the couple collateral victims of the remnants of the first poisoning?
