Ukraine’s intelligence agency, the Secret Service of Ukraine (SSU), said Monday that it had arrested a woman in connection with an alleged assassination plot against President Volodymyr Zelenskyy. The woman in question “was preparing a Russian airstrike in the Mykolaiv region during the visit of the President of Ukraine,” the SSU said.

“Primarily, the woman tried to establish time and list of locations of the Head of State’s tentative itinerary in the region,” a statement from the SSU said, referring to a planned visit by the president to the southern region.

The report from Kyiv’s intelligence community came as Russian forces struck the southern Ukrainian city of Kherson in the south, and border areas in the northeast Kharkiv region, with at least three people killed in the attacks, according to Ukrainian officials.
