The United States has prepared a draft with new sanctions against Russia in connection with the incident in the British city of Salisbury, Bloomberg reported, citing sources.
According to Bloomberg, the new package of restrictions is awaiting the approval of the White House.
Among the spheres that will be affected by the new sanctions, the Bloomberg sources listed "banking sanctions, prohibition on procurement of defence articles, aid money".
The US Treasury did not immediately comment on the matter.
The first batch of anti-Russian sanctions imposed by Washington in connection with the poisoning took effect in August.
Pompeo Told Lavrov in February of New Anti-Russia Sanctions Over Skripal Case — White House
A White House spokesperson told Sputnik that US Secretary of State Mike Pompeo had notified Russian Foreign Minister Sergei Lavrov in February that the United States would impose a new round of sanctions against Russia with respect to the Skripal case.
"As you know, the Secretary of State had a call with Lavrov in February and informed him that the United States will be taking CBW [Chemical and Biological Weapons Control and Warfare Elimination] Act-related action", the official said.
Although both Sergei and Yulia Skripal are claimed to have recovered from the attack, Russian diplomats working in the United Kingdom say that no one has personally seen them since last March and that the fate of the Russian nationals, therefore, remains unknown.
