As Russia continues to threaten a full-scale military invasion, the Ukrainian parliament on Wednesday approved a draft law giving citizens permission to carry firearms and act in self-defense — and within hours, gun stores were bustling.

Reuters reported that the draft measure was approved on “the first reading.”

Its authors reportedly stated in a note that “the adoption of this law is fully in the interests of the state and society,” adding that the law is needed due to “existing threats and dangers for the citizens of Ukraine.”
