Pro-choice campaigners say laws forcing women from Northern Ireland to travel to England for an abortion must be changed.
Northern Ireland's first-ever conference on abortion and clinical practice took place in Newcastle on Monday amid protests from a significant number of pro-life campaigners.
The protesters lobbied the controversial event, which they claimed should not have been allowed to go ahead as Northern Ireland remains the only part of the UK where abortion is illegal.
Bernie Smyth from Precious Life said: "It is outrageous that an abortion conference was held in Northern Ireland. Abortion is illegal here. Precious Life has asked the PSNI to investigate the legality of this conference."
However, Dr Audrey Simpson from the Family Planning Association said: "Women's lives in Northern Ireland are damaged by our restrictive abortion practices."
