German Foreign Minister Annalena Baerbock warned Tuesday that Ukraine “urgently” requires further air defense systems to protect itself against Russian strikes.

“Russian rocket terror, constant air alerts, permanent power outages, hardly any water: The situation in Ukraine has once again escalated dramatically with the massive Russian air strikes on the civilian infrastructure and the brutal Russian offensive in the Kharkiv area,” Baerbock said in a press statement during her trip to Kyiv.

“To protect Ukraine from the Russian hail of missiles and drones, it urgently needs more air defense. That’s why, together with [German] Defense Minister Pistorius, I launched a global initiative for more air defense,” she added.

So far, this amounts to an additional €1 billion to support Ukraine’s aerial protection, she explained.
