The Conflict between Russia and Ukraine, known as the Russo-Ukrainian War, has been ongoing since 2014. Here is a brief overview of the situation up to that point:

The conflict began in 2014 when Russia annexed Crimea, a region in Ukraine, following a controversial referendum. The annexation was widely condemned by the international community, and many countries, including the United States and the European Union, imposed sanctions on Russia in response.

After the annexation of Crimea, tensions escalated in eastern Ukraine, particularly in the Donetsk and Luhansk regions, where pro-Russian separatist movements emerged. The separatists, with alleged support from Russia, declared independence and engaged in armed conflict with Ukrainian forces.

Despite several attempts at ceasefires and peace negotiations, the situation remained volatile, with frequent ceasefire violations and casualties on both sides. The conflict has had a devastating impact on civilian populations, causing loss of life and significant humanitarian challenges.

Russia has faced accusations from Ukraine and the international community of providing military support to the separatist forces in eastern Ukraine. However, Russia has repeatedly denied direct involvement in the conflict, referring to the separatists as "self-defense forces" and arguing that any Russian military personnel fighting in Ukraine are there as volunteers and not under official Russian command.

The situation has been a major point of concern in international relations, leading to sanctions against Russia, diplomatic efforts to mediate a resolution, and support for Ukraine's sovereignty and territorial integrity from various countries.
