Delhi Blast Suspect Linked to Terror Group Using Telegram for Coordination

Imagine a popular phone app where people can chat privately, called Telegram.

It's used by millions for safe messaging, and even by leaders to talk to their people.

However, some bad groups also use this app.

They like it because it's private and hard for others to see what they're doing.

Terrorist groups have used Telegram to plan bad things, like attacks.

One doctor in Delhi, who was thought to be a suicide attacker, was connected to a terror group and may have used Telegram to communicate.

While Telegram says it tries to remove bad content and follows rules, critics say its privacy focus makes it easy for criminals and terrorists to organize.

The company says privacy is very important and they don't have many people to watch everyone, but they do remove harmful stuff when they find it.
