US officials have signalled concerns that Russia could use chemical weaponry during its assault on Ukraine.
Biden personnel have reportedly determined that Vladimir Putin would use chemical weapons before pushing for the nuclear option.
Politico unveiled the fears, which came from six people “with knowledge of the matter”, as officials ramped up preparations for escalation in Ukraine.
Those cited by the publication included US and Defense Department officials, who spoke under condition of anonymity.
They added that the US does not have intelligence that suggests such an attack is imminent.
The warnings underline a recent push from the Biden administration to prepare for their potential use.
Officials reportedly hope to gather support and resources to shore up chemical detection systems.
One of those speaking to Politico underlined the difficulties foreign powers face while attempting to identify chemical weapon traces overseas.
