Sergei and Yulia Skripal have slim chance of survival, says niece Read more 
 
 Local police have retaken control of The Maltings shopping centre, where the Skripals were first discovered, and London Road cemetery from counter-terrorism detectives, where officers focused their investigation into the nerve agent attack in previous weeks. Counter-terrorism detectives will continue to focus their inquiries on the home address for the coming weeks, and possibly months, after the father and daughter were found unconscious on a park bench in Salisbury earlier this month.

 "Those living in the Skripals' neighborhood can expect to see officers carrying out searches as part of this, but I want to reassure them that the risk remains low and our searches are precautionary," Deputy Assistant Commissioner Dean Haydon said in a statement. The unique circumstances of this investigation means that officers are likely be in the area for several weeks and months.” 
 
 About 250 counter-terrorism detectives continue to work around the clock on the investigation, supported by a full range of experts and partners. Officers continue to trawl through more than 5,000 hours of CCTV and examine more than 1,350 exhibits that have been seized. Approximately 500 witnesses have been identified and hundreds of statements taken. Traces of the nerve agent have been found at some of the other scenes detectives have been working at over the past few weeks, but at lower concentrations than that found at the home address. In response to the poisoning, more than 150 Russian officials have been expelled from more than 25 countries, and the UK government is considering further measures to punish Russia, including a ban on the City of London from selling Russian sovereign debt. Public health experts are still working to establish whether the nerve agent attack presents a long term risks to Salisbury’s residents, which will receive a £1m support package from central government to help recover.
– The military-grade nerve agent that left former Russian double agent Sergei Skripal and his daughter near death appears to have been left on his front door in Salisbury, England, police say. Investigators say the Skripals first came into contact with the nerve agent at Skripal's home, and the highest concentration of it was found on the door, the Guardian reports. Skripal and his daughter, Yulia, were found unconscious on a bench at an outdoor shopping complex on March 4. Detective Sergeant Nick Bailey, who was hospitalized for more than two weeks after the incident, is believed to have become sick after visiting the Skripal house, where he was one of the first on the scene, reports the Telegraph. Police say residents of Skripal's neighborhood can expect more searches in the area, but "the risk remains low." Britain blames Russia for the attack. It has expelled 23 Russian diplomats and numerous other countries, including the US, have followed suit. In a speech late Wednesday, British Foreign Secretary Boris Johnson thanked Britain's allies "from the bottom of his heart," CNN reports. "I believe that these expulsions represent a moment when a feeling has suddenly crystallized, when years of vexation and provocation have worn collective patience to (the) breaking point, and when across the world—across three continents—there are countries who are willing to say enough is enough," he said.
