A Ukrainian MP has told Sky News that her country's invasion into Russia's Kursk region should send a "very clear message" to NATO members that Ukraine needs long-range weaponry.
Maria Mezentseva says Ukraine wants the ability to use such weapons to strike air bases and missile launch sites deep into Russian territory.
If it had this, Ms Mezentseva says, Ukraine would not have been "forced" into creating a "buffer zone" inside Russia.
