Police have been asked to act over a replica of a mosque on top of a bonfire in County Tyrone.
The bonfire, in Moygashel, has featured other controversial displays in the past.
Patrick Corrigan from Amnesty International called it “a blatant attempt to stir up anti-Muslim hatred and intimidate local families”.
He said it needed to be met with a “decisive response” by the police.
“The placing of an effigy of a mosque on top of a bonfire amounts to incitement to hatred directed at real people who live, work and raise families in Northern Ireland,” he said.
Bonfires are lit annually in some unionist areas across Northern Ireland in July to usher in the Twelfth of July, the main date in the parading season.
The majority are lit on 11 July, known as the Eleventh night.
The Twelfth commemorates the Battle of the Boyne in 1690 when the Protestant King William III defeated Catholic King James II.
