The leaders of the United States, France, Germany and Britain have said they are united in blaming Russia for a nerve agent attack on former spy Sergei Skripal, urging Moscow to disclose details of a Soviet chemical weapons programme, APA reported citing France 24.
In a rare joint statement, President Donald Trump, President Emmanual Macron, Chancellor Angela Merkel and Prime Minister Theresa May said "there is no plausible alternative explanation" to Russian responsibility in the March 4 attack in England.
"We, the leaders of France, Germany, the United States and the United Kingdom, abhor the attack that took place against Sergei and Yulia Skripal" in Salisbury, said the statement issued by the British government.
The four leaders said Russia's failure to respond to Britain's "legitimate request" for an explanation "further underlines its responsibility", describing the use of a chemical weapon as "an assault on UK sovereignty" and "a breach of international law".
Britain has expelled 23 Russian diplomats and suspended high-level contacts with Moscow over the incident. Russia is expected to take retaliatory measures soon.
Earlier on Thursday, May won the support of France's Macron, whose administration had initially appeared reticent to accuse Russia directly.
