Now let's move to the UK for the latest development on an earlier nerve agent attack. British Prime Minister Theresa May says the two men facing charges in the case are officers from the Russian military intelligence service. While Moscow says it is skeptical and questions the credibility of the evidence. CGTN's Dan Ashby reports from the Russian capital.

They're accused of being Russian military spies who carried out the Salisbury attack. Despite the release of closed-circuit TV images of these two men near the victims' home? Moscow says it remains skeptical. It says it's not being allowed access to the British investigation and cannot verify the evidence.

MARIA ZAKHAROVA SPOKESWOMAN, RUSSIAN FOREIGN MINISTRY "A Russian citizen that enters Britain from Russia needs to have, in order to receive a British visa, a huge number of papers and documents, and most importantly, must leave copies of their fingerprints with the embassy. We have requested copies of the fingerprints which the British government, naturally, has refused to give us like with all the other material we have previously requested."

Russia's Foreign Office describes the naming of the suspects as quote "another hellish merry-go-round".

VIACHESLAV MATUZOV FORMER RUSSIAN DIPLOMAT "Two persons! What kind of persons? Their names are not real, I'm sure. They say themselves. Well, if you don't know people, if you don't know the families, how do you blame Putin?"

And on the streets, many Russians share that view.

"No, of course, it's not true. If Russia did it, there would be some evidence by now."

"This is all nonsense, it's a lie. They want to label our country and give it a bad reputation, but we will come through it."

"It doesn't make any sense. There's no point in Russia doing this. Why would they set a spy free and then kill him?"

DAN ASHBY MOSCOW "All along Russia has denied any involvement in the attack, and it says those two names mean nothing to Moscow authorities. So it will continue to demand access to the UK investigation, but that's unlikely to happen. Dan Ashby, CGTN, Moscow."
