Ukraine's security service said it foiled a Russian attempt to assassinate President Zelenskyy.
By tracking a woman, it said it learned she was trying to share information on Ukraine's arms locations.
The woman was arrested on Monday after Ukraine learned the extent of her "treason," the armed forces spokeswoman said.
The armed forces spokeswoman said she was "turned collaborator by FSB agents and continued to work for them."
Ukrainian officials and lawmakers told Politico this month that Ukraine has a plan in place if Zelenskyy is killed.
