Volodymyr Zelenskyy has said Romania's decision to provide his country with two Patriot air defence systems will strengthen security in Ukraine and throughout Europe.
"This crucial contribution will bolster our air shield and help us better protect our people and critical infrastructure from Russian air terror," the Ukrainian president said on X.
The Patriot, which stands for Phased Array Tracking Radar for Intercept on Target, is a surface-to-air missile defence system.
For months now, Ukraine has been calling for countries to provide more air defence systems to help protect it from Russian attacks.
