The British government is seeking an urgent meeting of the United Nations Security Council to update members about the attack on former double agent Sergei Skripal.

Skripal and his daughter Yulia were found slumped on a bench in Salisbury on March 3. British authorities claim both were poisoned with a Soviet-engineered nerve agent called Novichok. Both remain in critical condition in hospital.

The Foreign Office tweeted Wednesday morning that the British government has called for an urgent UNSC meeting over the attack. Prime Minister Theresa May alleges that it was either authorized by the Russian government or Moscow allowed the nerve agent to fall into the wrong hands.

May set a deadline of midnight Tuesday for Russia to provide an explanation for the "poisoning" of Skripal and his daughter, and expelled 23 Russian diplomats when the deadline was missed. Speaking on Wednesday, Russian Foreign Minister Sergey Lavrov said Russia is ready to respond to to any official request from London but Moscow has yet to receive any such contact regarding the case. Moscow denies any involvement in the incident.

Allegations, not confession, are merely the queen of evidence of the UK," the minister said at a press conference. "We will uphold international law and we don't see that our British partners have any arguments on the case," he added.

Lavrov said the case must come before the Organization for the Prohibition of Chemical weapons (OPCW), of which both Russia and the UK are members.
