COREN: Nearly 200 British troops are helping police investigate the mysterious nerve agent attack in Salisbury, Southern England. That's where someone poisoned former Russian spy, Sergei Skripal, and his daughter, Yulia. They are fighting for their lives in hospital. Western intelligence services consider Russia a leading suspect, though they warn it's still too early in the investigation to say for sure. On Friday, British troops deployed to Salisbury to find out more. Our CNN's Phil Black has the details.</s>PHIL BLACK, CNN CORRESPONDENT: The military support is coming from different services, the army, air force and Marines, different units with different capabilities and expertise. We're told some of that expertise includes chemical warfare and decontamination. The police say they've asked for this help in order to deal with -- remove some objects, including cars, implying there is some ongoing concern about the possibility of contamination from the nerve agent. But authorities here say the health advice to the public is still the same. They don't believe there is any wider ongoing risk. Meanwhile, police were also seen at the local cemetery in protective clothing, studying the graves of Sergei Skripal's wife and son. A close friend of family tells CNN that Skripal's wife, Lyudmila, died in 2012 at the age of 60 from cancer; his son, Alexander, passed away just last year at the age of 43 from liver failure. The police say they're not disturbing the graves. They're not exhuming any remains. The forensic focus is simply on the grave sites themselves. This is all part of the ongoing effort as investigators here try to determine how and where the nerve agent was deployed in this small English city -- Phil Black, CNN, Salisbury, Southern England.</s>COREN: Coming up, Turkey says it's close to a major victory in Syria's Afrin region.
