Personnel in protective coveralls and breathing equiptment cover an ambulance with a tarpaulin at the Salisbury District Hospital in Salisbury, southern England, on March 10, 2018, in connection with the major incident sparked after a man and a woman were apparently poisoned in a nerve agent attack. British soldiers were deployed on March 9 to help a counter-terrorism investigation into a nerve agent attack on former Russian spy Sergei Skripal, as speculation mounted over how London could retaliate if the Russian state is found to be responsible. Skripal and his daughter Yulia remain unconscious in a critical but stable condition following the March 4 attack in the sleepy south-western English city of Salisbury.

Russia's state-owned RT network on Thursday aired an interview with the two men suspected by UK authorities of poisoning former Russian spy Sergei Skripal and his daughter, one day after Russian President Vladimir Putin encouraged the suspects to speak to the media. In an interview with RT editor-in-chief Margarita Simonyan, two men who identified themselves as Alexander Petrov and Ruslan Boshirov said they had nothing to do with the poisoning of the Skripals in Salisbury, England, saying they had reached out to RT to tell their side of the story.
