British Prime Minister Theresa May updated the House of Commons on the investigation into the nerve agent attack against Russian former double agent Sergei Skripal and his daughter this afternoon, stating that "the [British] government has concluded that it is highly likely that Russia was responsible for the act against Sergei and Yulia Skripal."

What's next: May said that Foreign Secretary Boris Johnson had summoned Russia's ambassador to provide an explanation for the use on British soil of a nerve agent manufactured by the Russian government — with an acceptable response required by Wednesday:

QuoteShould there be no credible response, we will conclude that this action amounts to an unlawful use of force by the Russian state against the United Kingdom.
