21 killed in blast horror

TWENTY-ONE people were killed and 182 were injured when two bombs ripped through two Birmingham pubs on November 21, 1974.

Six Irishmen were arrested within hours of the IRA blasts, and in 1975 sentenced to life imprisonment for the bombings.

The men – who became known as the Birmingham Six— maintained their innocence throughout.

After a lengthy campaign, their convictions were declared unsafe and quashed by the Court of Appeal in 1991.

The episode is seen as one of the worst miscarriages of justice in British legal history.
