Several thousand people gathered in Dublin city centre today for a pro-life rally.
The crowds assembled at Parnell Square at lunchtime, before marching down O'Connell Street and onto Custom House Quay.
The Rally For Life was the first in-person march to be held since 2019 because of Covid restrictions.
Organisers said the chief aim of the rally was to urge the public, and the Government, to rethink abortion.
A campaign to retain the three-day waiting period before undergoing an abortion was launched at the rally.
Megan Ní Scealláin, a spokesperson for the Life Institute, said: "Voters were guaranteed that women would have a three-day period to reflect between a first abortion appointment and the doctor giving the abortion pill, and it is appalling to see abortion campaigners now push to have that time to think scrapped.
"We know from figures released to Carol Nolan TD that between 800 and 1,000 women did not proceed with an abortion after that initial appointment.
"Scrapping the requirement for those three days to think might mean another 1,000 abortions a year."
Pro-life TDs, Independent Carol Nolan and Peadar Tóibín of Aontú, also addressed the rally.
Last week, the US Supreme Court overturned the constitutional right to the procedure across America.
The move ended the right to abortion in a seismic ruling on one of the most divisive and bitterly fought issues in American political life.
