US Ambassador Jon Huntsman was summoned to the Foreign Ministry to be told of the decision, Lavrov said. Russia also urged the Organization for the Prohibition of Chemical Weapons (OPCW) to hold an emergency meeting next week to investigate the case.

Mr. Lavrov said Russia will make a reciprocal response and wants to make a consular visit to Skripal’s daughter to investigate the incident.
