How do I talk to my young teen who is anxious about the current wars all over the world?

We are not in a country directly at war. So far it hasn’t affected us at all except some LPG shortage. I do want my teen to continue caring about the world but I also wish to take care of their mental health. How do I draw the line between protecting them and allowing them to build their resilience? Are there any good resources out there which they can use instead of the regular news which is catered towards adults who have (or should have) better filters.

They are 14. Love reading, dancing and art. Very sensitive. Has a group of close friends.
