A request by the Irish Republican Party, Sinn Fein, to open a book of condolence in Belfast city council for Palestinians killed in Gaza last week was blocked by Unionists allied with the Northern Ireland Friends of Israel group.

Denouncing the book of condolence as “deeply shameful”, the Israeli lobby group accused Sinn Fein of supporting terrorists for wanting to mark the killing of Palestinians by Israeli occupation forces in Gaza.

The two main Unionist parties, who have strong ties with the pro-Israel lobby group, blocked the request, which forced Sinn Fein to open an internal book of condolence. According to the rules, a book of condolence can only be opened with the agreement of all parties at City Hall.

The Belfast Telegraph reported that the Social Democratic and Labour Party (SDLP) council group leader Tim Attwood said he was “disappointed” that Unionists blocked the book of condolence “to mark the killings and injuries inflicted on the people of Gaza”.

“People of Belfast are horrified and wish to express their sympathy at the tragic loss of life,” he added.

Meanwhile, Sinn Fein group leader on the Belfast City Council, Deirdre Hargey, was reported as saying that her party would be opening its own book of condolence in the party’s room at City Hall, open to all members of the public.

The request for the book of condolence came after a number of Palestinian solidarity protests were held across Northern Ireland last week. Sinn Fein reacted to the killing and the pro-Palestinian demonstration by also demanding the expulsion of the Israeli ambassador.

This is the second time in two months that the plight of Palestinians became a cause of tension in Belfast. In March the Northern Ireland Friends of Israel group invited the Israeli ambassador to the UK, Mark Regev, to speak at an event in the local public library. Activists denounced the decision saying that Regev “has a long history of excusing, apologising and justifying [Israel’s] murder, torture and genocide as well as land theft from the indigenous population of Palestine.”

Members of the community in Belfast who supported the decision to open a book of condolence were disappointed by the Unionist parties. They told MEMO that many Unionist politicians and councillors were members of the Friends of Israel and revealed that Unionist parties have all hosted friends of Israel events.
