The family of a young man killed in the Manchester Arena bombing have joined others affected by terrorism to set up a new campaign group.
29 year old Martyn Hett was one of the 22 people murdered in the Manchester Arena attack.
His brother and mother have helped to found the 'Survivors Against Terror' group, which launches today.
Its members want better support and more effective government policies to tackle terrorism.
The group plans to conduct a survey of those affected by terrorism, and to go into schools to talk to children about the impact of hatred.
They want to make sure support is consistent for victims across the country.

In the days following the Manchester Arena bomb attack, the phrase 'Be More Martyn' was used on social media to remember one of the 22 victims.
Martyn Hett from Stockport had thousands of Twitter followers who loved his posts about popular culture and his active social life.
Now, some of his many friends have shared their memories for a new play, called 'Be More Martyn'.
Andrew Fletcher went along to final rehearsals.
