A councillor on Derry City and Strabane District Council has said that a decision to light up the council building in Palestinian colours is to "support terrorist Hamas".
DUP councillor David Ramsey made the comments on Twitter after the council agreed to light the building in Palestinian colours at a special council meeting in Derry on Monday.
"It's really in support of terrorist Hamas in their attempted invasion of Isreal," he said.
Hamas are a Palestinian fundamentalist organisation which seeks to recover land lost to Israel using military force.
More than 60 Palestinian demonstrators were killed and more than 2,000 were injured by Israeli defence forces in the area in recent weeks.
The motion was passed by 22 votes to one.
Independent Unionist Maurice Devenney was the only dissenting voice against the move.
DUP councillors did not attend the meeting saying they were 'too busy with local issues to waste an afternoon' discussing 'something we have no control over'.
"The DUP will not be attending a special meeting today to discuss Palestine, this is another attempt to take sides and support Hamas terrorists who are the real problem in the region," a DUP statement said.
The council is also to consider the expense of writing to every home and business in the council area to inform them of the products on the BDS boycott of Israeli products list.
Councillors supported a proposal from Sinn Fein councillor Sandra Duffy to look at the costs of posting out a leaflet to every house and business with the information, which had been proposed by independent councillor Paul Gallagher.
