Three men have been found guilty of planning to plant bombs in the UK which could have killed hundreds of people.
Abdulla Ahmed Ali, Assad Sarwar and Tanvir Hussain were all convicted of planning to make bombs using chemicals.
One man, Mohammad Gulzar, was found not guilty of any terrorism charges. The jury couldn't make up their minds about four other men who were also accused.
