Moscow rejects UK's ultimatum

MOSCOW, Mar 13 (AFP): Russia on Tuesday rejected Britain's demand that Moscow provide an explanation over the poisoning of an ex-double agent and said London should provide Moscow with access to the nerve agent.

"Before giving ultimatums it's better to honour your own obligations on international law," Lavrov told reporters, referring to the Chemical Weapons Convention.

Russia's top diplomat said that Britain should have sent Moscow an official request about the substance used on its soil.

Lavrov said Russia had not received such a request and also demanded to be given access to the Russian-made nerve agent used to poison former double agent Sergei Skripal and his daughter Yulia.

"Through an official note we had demanded access to this substance," Lavrov said, adding that Russia also asked to be informed about the investigation. "Our requests have been denied."

"If the procedures stipulated by the convention will be implemented I assure you that Russia will fulfil its obligations," Lavrov said.

He insisted that Moscow was not to blame for the poisoning of the former agent said it was ready to cooperate with London.
