British prosecutors indicted two Russian men for the poisoning by neurotoxic agents of former spy Sergei Skripal and his daughter Yulia in the English town of Salisbury.
The Crown Prosecution Service says that Alexander Petrov and Ruslan Boshirov are accused in absentia of conspiracy to commit murder, attempted murder and use of nerve agent Novichok.
Prosecutor Sue Hemming said they had considered the evidence and concluded that "there is sufficient evidence to provide a realistic prospect of conviction and that it is clearly in the public interest to accuse Alexander Petrov and Ruslan Boshirov, who are Russian citizens."
However, he said that the United Kingdom did not ask Moscow to extradite the men because Russian law prohibits the extradition of the country's citizens.
Russia has denied any involvement in the March incident and suggested that the British security services carried out the attack to stoke the hysteria against Moscow.
The police detail the movements of the suspects
Metropolitan police say the two men arrived at the Gatwick airport from Moscow on March 2.
They stayed at a hotel in East London before traveling to Salisbury two days later.
The police have requested information about the two men, urging anyone who has seen them to contact the police.
British Prime Minister Theresa May will make a statement on the matter in Parliament soon.
More to come.
