The lone survivor of an IRA massacre of ten Protestant workers believes state agents may have been involved, a coroner's court has heard.
On Monday, a solicitor for Alan Black made the claim at the preliminary hearing of a new inquest into the Kingsmills shootings.
The victims were all textile factory staff who were shot dead when an IRA gang ambushed their mini-bus near the County Armagh village of Kingsmills in 1976.
