The U.K. is asking Russia to shed some light on the nerve agent attack on a former double agent and his daughter after two British citizens were sickened by the same poison over the weekend.
During an interview on BBC Radio 4 Thursday, British Security Minister Ben Wallace called on Russia to provide details about the original novichok attack on Sergei and Yulia Skripal in March.
"The Russian state could put this wrong right. They could tell us what happened, what they did and fill in some of the significant gaps we are trying to pursue," Wallace said.
Authorities are still working to determine how a man and a woman in Amesbury came into contact with the same deadly nerve agent months after the Skripals were poisoned.
But Wallace said they could be "victims of the consequences of the previous attack."
Russia has repeatedly denied any involvement in the March attack and said on Thursday it had nothing to do with the most recent incident. A spokesperson for the Kremlin added it had offered to help Britain investigate the attack on the Skripals long ago, but the U.K. didn't accept.
