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.

Stormont's deputy First Minister resigned from the Westminster role in December.
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.
Martin McGuinness has described meeting the Queen as, "very nice."
Martin McGuinness has said that, "it was nice" to meet the Queen and that the meeting went, "very well" as he left the Lyric Theatre this afternoon.
He also added, "I'm still a Republican."
Northern Ireland Secretary Owen Paterson met Mr McGuinness this morning and added that he was relaxed.
He said the Deputy First Minister greeted the Queen in Irish and their meeting was cordial.
It had obviously gone very well.This will move Northern Ireland on to a whole new plane. After all the trauma of Northern Ireland, everyone is looking forward.It is about a shared future, not a shared-out future.
None of this could have happened a few years ago so it is all looking to the future.
He said it was absolutely appropriate that when the Queen visits parts of the UK, she meets local politicians, democratically elected, pursuing their democratic political goals by peaceful means.
Mr Paterson added that it built on the success of the Queen's visit to the Republic of Ireland last year.
The Queen is expected to visit Stormont later today.
