Police kept a close eye as pro-choice activists delivered abortion pills to women in Northern Ireland using a drone.
The stunt, described as an act of solidarity, aimed to highlight the strict laws around terminations that exist on both sides of the Irish border.
Courtney Robinson, 18, from Belfast, who took the tablets, said: “We are here to say we are going to defy the law in helping women obtain these pills and we are going to work to make the law unworkable and stand in solidarity with all women who want to have an abortion and have the right to do so in Northern Ireland.”
The drone flight started at Omeath in Co Louth and landed a short distance away, near Narrow Water Castle in Co Down, shortly after 10am.
Ms Robinson, a member of Labour Alternative, added: “The reason we are doing this is to highlight that these pills are available to women who are not able to travel outside of Northern Ireland for an abortion.”
Abortion protestors in Northern Ireland have frequently staged stunts in the full glare of the public eye in recent years, in which they effectively invite police to take action against them by claiming to have procured or taken abortion tablets.
On Monday, anti-abortion group Precious Life said it had written to the PSNI chief constable about the drone stunt.
Bernadette Smyth, its director, had said: “I have requested that the PSNI confiscate the ‘abortion drone’ and take in for questioning the people behind it, as they may be aiding and abetting women to break the law in Northern Ireland.
“It is my hope that the PSNI will intervene tomorrow and do everything in its power to keep women and their unborn children safe in Northern Ireland.”
A number of uniformed and plain clothes police officers who were at the landing site spoke to organisers and recorded events on video. However, no action was taken to confiscate the medication, which had been prescribed by a doctor.
Traffic was also stopped on the main road while the drone was in the air.
The drugs, Mifepristone and Misoprostol, can be taken up to nine weeks into a pregnancy and have been approved for use by the World Health Organisation since 2005.
Lucy Simpson, from Belfast, who also took tablets, said legal reform was urgently needed.
She said: “The law is archaic. We are governed in Northern Ireland by an Act which is dated 1861, which is in the dark ages, it’s like when dinosaurs were on earth. We think it should be changed radically and we can’t really wait any longer.
“Thousands of women suffer every year in Northern Ireland and the Republic having to travel abroad for abortions and go through very traumatic times.
“We feel now is the time to change legislation.”
The event was organised by a collaboration of pro-choice groups, Alliance For Choice; Rosa; Labour Alternative and Women On Waves, which staged a similar flight from Germany into Poland.
The groups said no laws had been broken, adding in a statement: “The ‘abortion drone’ will mark the different reality for Irish women to access safe abortion services compared to women in other European countries where abortion is legal.”
In Northern Ireland, the maximum penalty for the crime of administering a drug to induce miscarriage under the relevant law, namely the Offences Against The Person Act 1861, is life imprisonment.
In April a 21-year-old woman was handed a suspended sentence by a judge in Belfast after she bought drugs on the internet to induce a miscarriage because she could not afford to fly to England.
In the Irish Republic, the offence of procuring an abortion carries a potential 14-year jail term.
Pro-life organisations had vowed to do all in their power to stop the drone, but there was no protest at Narrow Water.
