Police to launch murder investigation into Bloody Sunday
The police are to launch a murder investigation into the deaths of 13 people shot dead by soldiers in Londonderry on Bloody Sunday in 1972.
The move comes after the PSNI and Public Prosecution Service reviewed the findings of the Saville inquiry, which said none of those killed was armed.
The police investigation is expected to take at least four years and involve a team of 30 detectives.
Police have said no decision has been made as to when it will start.
