The Facebook-owned social media app have created a button that aims to restricts abusive and offensive messages being shared between users.

The firm's chief executive Adam Mosseri admitted that there is "more" they can do to prevent bullying.

He wrote in a blog post: "We can do more to prevent bullying from happening on Instagram, and we can do more to empower the targets of bullying to stand up for themselves.

"These tools are grounded in a deep understanding of how people bully each other and how they respond to bullying on Instagram, but they're only two steps on a longer path."

An example of the tool shows a message reading,

"you are so ugly and stupid", and then a warning comes up which reads: "Are you sure you want to post this?"

The user can then click on a "learn more" button and a note says: "We are asking people to rethink comments that seem similar to others that have been reported."

The tool will be made available in English-speaking continues first, with plans to make it a global action.

Instagram added: "We have found that it encourages some people to undo their comment and share something less hurtful once they have had a chance to reflect."
