Ukrainian President Volodymyr Zelensky said in a video message on Tuesday that Ukrainian forces "destroy the invaders wherever we can." Individual messages can be fully encrypted.

It's not automatic, as it is on Signal and WhatsApp. Such instructions could actually endanger people — citizens receive air strike warnings via smartphone alerts.

Private groups cannot be seen by other Telegram users, but Telegram itself can see the groups and all of the communications that you have in them. All of the same risks and warnings about channels can be applied to groups.
