It's so sad that they are caught up in a war just because of where they lived.
ご質問ありがとうございます。
この文章の英訳が様々にあります。「かわいそう」はpitifulとかsuch a pityとかsadなどに訳せますが、pitifulとsuch a pityは批判みたいな良くないニュアンスがありますので、使わない方がいいと思います。「巻き込まれる」はto be involved inとto be caught up inに訳せます。
例文：They were living in peace, but all of the sudden they're caught up in a war just because of where they lived.
ご参考になれば幸いです。
