NATO foreign ministers said all member nations were united in their resolve to support the Ukrainian military. This comes amid growing calls for Russia to be held accountable for atrocities in the suburbs of Kyiv.

The ministers met in Brussels on Thursday.

NATO Secretary General Jens Stoltenberg said, "We agreed that we must further strengthen and sustain our support to Ukraine so that Ukraine prevails in the face of Russia's invasion."

Ukraine's Foreign Minister Dmytro Kuleba was also in attendance. He said Ukraine would use military aid to fight not only its own security, but the security of all of NATO.

Kuleba said, "I'm speaking about days, not weeks, or your help will come too late and many people will die, many civilians will lose their homes, many villages will be destroyed."

NATO says it expects larger attacks in eastern Ukraine, where Russia is focusing its offensive. Ukraine says this underscores the need for more weapons as soon as possible.
