Campaign group Survivors Against Terror, the Guardian reports, will on Wednesday (November 21) publish the findings of its interviews with some 270 people affected by terrorism.
These include relatives of those killed in the 2015 Sousse attack, in which 30 Tui holidaymakers were gunned down on the beach in the Tunisian holiday resort.
The report, Giving Voice to Survivors, also aims to highlight the experiences of those actually caught up in such attacks.
