Sinn Fein leader Gerry Adams said he will attend a parade in west Belfast later today to "support the families of the Ballymurphy massacre".
Ahead of the march, Adams said he believes an independent panel should be appointed "to examine all of the documents relating to the context, circumstances and aftermath of the deaths" of 11 people during the Troubles.
Belfast's Lord Mayor, Sinn Fein's Mairtin O'Muilleor, has been attacked by loyalist protesters at the re-opening of a children's park in north Belfast.
Mr O Muilleoir, 53, required a police escort to evade angry protesters at the re-opening of a park in the staunchly unionist Woodvale area.
The high-profile businessman and city councillor said he was kicked and punched during the altercation. Police said nine of their officers were injured during the incident, although none required hospital treatment.
Community tensions are high in Woodvale after recent loyalist rioting over a decision to prevent three protestant Orange Order lodges parading past the nearby nationalist Ardoyne area.
Loyalists have accused Sinn Fein of waging a cultural war against their community.

Sinn Fein leader Gerry Adams has criticised Lady Thatcher, saying "her Irish policy failed miserably":
Margaret Thatcher did great hurt to the Irish and British people during her time as British Prime Minister.
Working class communities were devastated in Britain because of her policies.
Her role in international affairs was equally belligerent whether in support of the Chilean dictator Pinochet, her opposition to sanctions against apartheid South Africa; and her support for the Khmer Rouge.
Here in Ireland her espousal of old draconian militaristic policies prolonged the war and caused great suffering.
Margaret Thatcher will be especially remembered for her shameful role during the epic hunger strikes of 1980 and ’81.
Her Irish policy failed miserably.
Paul Maskey, Sinn Fein MP for West Belfast says the community is shocked by the murder of a young father of one on Saturday night.
"Those who carried out this shooting should be ashamed of themselves" he said. "People are shocked that this is the Easter holiday period and people were in good form and someone, last night, was willing to go out and take the life of another individual".
Northern Ireland's Justice Minister David Ford has also condemned the murder. "There can be no cause that can justify the taking of a precious human life and no excuse can explain the suffering that results" he said. Both politicians urged any witnesses to the attack to speak to the police.

The Queen and the Duke of Edinburgh were met by cheering crowds as they travelled in an open-top car to The Parliament Buildings in Stormont, as part of her visit to Northern Ireland.
Twenty thousand people have gathered for a garden party with the Queen this afternoon and I think if we spoke to them, then the overwhelming majority are happy with what happened; welcome that handshake and see it as good step for the future of this country.
Having said that there are others who don't, dissident Republicans who feel that Martin McGuinness has sold out, and that Sinn Fein is doing this purely for political purposes.
There are also families who have suffered at the hands of the IRA. People who have lost husbands and wives, sons and daughters, who find it very uncomfortable to see a former commander of the IRA shaking hands with the British Queen.
Martin McGuinness has described meeting the Queen as, "very nice."
