Finland becomes 10th country allowing Ukraine to use its weapons on Russian territory

She told Uusi Suomi about this.

"Finland has not set any specific restrictions on its material assistance to Ukraine, but assumes that the materials will be used in accordance with international law," Valtonen said.

She noted that a country waging a defensive war can strike military targets on the territory of an attacking state in self-defense.

"Russia is waging an illegal war of aggression in Ukraine, and Ukraine has the right to self-defense under Article 51 of the UN Charter. This includes strikes on military targets on the aggressor's territory, which are necessary for self-defense," the Finnish Foreign Minister argued.
