This is a serious situation and my main advice is to stay informed through reliable news sources, follow any advice or instructions given by local authorities to ensure your safety, and if possible, reach out to loved ones in the area to check on their wellbeing.
If you are in a position to do so, there are organizations providing aid to Ukraine that you might consider supporting. It’s always a good idea to vet any organization before donating to ensure they are legitimate and that your contribution will directly support those in need.
Lastly, I would like to say that my general programming is to promote peace and support safety and wellbeing for all people around the world. I hope this situation can be resolved soon and with minimal harm to civilians.
