The decision follows months of wrangling over the symbolic case against the ex-paratrooper, identified only as "Soldier F", charged with murdering two civilians and the attempted murder of four others.

The decision by the PPS to halt the prosecution in 2021 proved deeply divisive in the UK-run province where decades of sectarian violence beginning in the 1960s continue to cast a long shadow.

British troops opened fire on a civil rights demonstration in the Northern Irish city of Londonderry on January 30, 1972, killing 13 people.

A 14th victim later died of his wounds.

Bloody Sunday, whose 50th anniversary was commemorated this year, has become synonymous with the worst violence in the period known as "The Troubles" which ended with peace accords in 1998.

In March, the High Court in Belfast overruled the decision by the PPS to drop the charges against Soldier F.

Earlier this month, the same court rejected the PPS's bid to have its appeal referred to the UK Supreme Court.

The PPS said following the decision to resume the proceedings, it had written to the families of the victims of Bloody Sunday as well as to Soldier F's legal representatives.

"I am very conscious of the upset caused to the Bloody Sunday families by the PPS decision to withdraw proceedings against Soldier F last year," Deputy Director of Public Prosecutions Michael Agnew said.

"The PPS is committed to progressing court proceedings against Soldier F without any further delay," he added.

Bloody Sunday, which saw the British Parachute Regiment open fire on a civil rights march in the majority Catholic Bogside area of Derry, helped galvanise support for the Provisional IRA early in the Troubles.

A 12-year public inquiry -- the largest investigation in UK legal history -- concluded in 2010 that British paratroopers lost control and none of the casualties posed a threat of causing death or serious injury.

The probe prompted then-prime minister David Cameron to issue a formal state apology for the killings, calling them "unjustified and unjustifiable".
