LONDON- UK Prime Minister Theresa May has issued a warning to Russia over the nerve agent attack on former Russian spy Sergei Skirpal.
Skirpal and his daughter Yulia were found collapsed at a park bench last week and later inquiries revealed that a nerve agent was used at the restaurant where they last ate, thus poisoning them.
May in her warning said Russia must explain by the end of Tuesday how a Russian made nerve agent came to be used in the attack. US Secretary of State Rex Tillerson also seconded May's assertions.
Mrs May told the Commons on Monday, "Either this was a direct action by the Russian state against our country, or the Russian government lost control of its potentially catastrophically damaging nerve agent and allowed it to get into the hands of others."
Nato secretary-general Jens Stoltenberg said: "The UK is a highly valued ally, and this incident is of great concern."
