The Green Brigade have defied a warning from Celtic not to display support for Palestine against Atletico Madrid in the Champions League.
Photos have emerged of a giant flag being set up in the north curve section of Parkhead, despite the club urging fans not to do so at the risk of a fine from UEFA.
The group were denied pre-match access to the stadium but this has not prevented them from organising a display.
The Green Brigade have shown support for Palestine across the years and have urged fans to join them in doing so amid the ongoing conflict with Israel.
Both Celtic and Atletico Madrid players will wear black armbands, as a show of respect and support for all those affected by the conflict tonight.
A club statement read: "We have witnessed death, violence and destruction in the Holy Land in recent weeks, with thousands of people - men, women and children - killed, injured and displaced.
"We are witnessing a tragedy of horrendous scale. As it continues, everyone at Celtic prays for all who have been affected.
"We also hope and pray for peace, and for humanitarian support to reach those who are in need and in fear.
"Many of our colleagues, supporters, friends and families have been affected by these events.
"Against this backdrop of conflict and pain, sport can promote peace and demonstrate humanity and empathy for all who continue to suffer.
"For the Club’s UEFA Champions League match against Atletico Madrid this evening, Celtic and Atletico Madrid players and coaching staff will wear black armbands, as a show of respect and support for all those affected by the conflict.
"The Club is also making a contribution to the International Committee of the Red Cross to support people affected by the humanitarian crisis in the region.
"The Club recognises that our supporters hold personal views to which everyone is entitled. As a club open to all, we all belong at Celtic Park.
"Celtic Park is where we come to support our football club. Recognising this, respecting the gravity of the tragedy unfolding and its impact on communities in Scotland and across the world, and in line with other clubs, leagues and associations, we ask that banners, flags and symbols relating to the conflict and those countries involved in it are not displayed at Celtic Park at this time.
"As we approach this crucial fixture, as ever, we sincerely thank our fans for their positive support of the players and the team.
"We thank you very much for your continued support of Celtic Football Club."
