 "UK police believe suspects behind Skripals' Novichok poisoning identified")
Police believe they have identified suspects who carried out the Novichok attack on a former Russian double agent and his daughter in the English city of Salisbury, the Press Association reported on Thursday.
"Investigators believe they have identified the suspected perpetrators of the Novichok attack through CCTV and have cross-checked this with records of people who entered the country around that time," a source told the Press Association news agency.
"They (investigators) are sure they (suspects) are Russian," the source added. Scotland Yard refused to comment on the report when contacted by AFP.
Ex-Russian spy Sergei Skripal and his daughter Yulia collapsed in Salisbury on March 4 after being exposed to the nerve agent Novichok. Both have since recovered.
Britain blamed Russia for the poisoning of Skripal, a former colonel in military intelligence who was jailed for betraying Russian agents to Britain's MI6 security service. He left Russia for England in a 2010 spy swap.
Russia has strongly denied involvement in the Skripal attack, sparking a diplomatic row that has led to tit-for-tat diplomatic expulsions between Britain and its allies and Russia.
