The British government has offered to pay compensation to the families of the victims of Bloody Sunday.
Paratroopers opened fire on protesters in Londonderry, Northern Ireland on 30 January, 1972.
They shot dead 13 Catholic civilians that day. A fourteenth died later.
Some relatives have already rejected the payout offer, insisting they want their loved ones’ killers to be prosecuted.
For years, Britain’s Ministry of Defence refused to accept any blame for the killings.
But last summer, an investigation carried out by one of the country’s leading judges concluded that the armed forces fired first and without provocation.
Prime Minister David Cameron then apologised to the families in parliament and called the shootings “unjustified and unjustifiable”.
