The Ukrainian Parliament on March 22 began enforcing a new law requiring lawmakers to check guns, explosives and other weapons at the door before entering the legislative chamber after a member arrived this month with a pistol and three hand grenades.
No law had prohibited the lawmaker, Nadiya V. Savchenko, from entering with the weapons, it turned out, but the episode unnerved her colleagues, spurred a prosecutorial inquiry over her intentions, and led to the adoption this week of the weapons prohibition.
