Ireland must act now. Our government has failed to defend international law, failed to protect Irish citizens detained in international waters, and failed to enact the Occupied Territories Bill. We demand action: 1️⃣ Implement the ICJ’s findings. 2️⃣ Enact the Occupied Territories Bill.

At an absolute minimum, Ireland must immediately pass the full Occupied Territories Bill (NOT the watered-down version) & end the transport of Israeli war matériel through Irish airspace. And every Irish voter should be calling their TD tomorrow to ensure it happens. www.ohchr.org/en/press-rel...

Please take this easy action, we must see sanctions on apartheid Israel for its genocide of Palestinians, we need, as a first step, the full Occupied Territories Bill enacted. #SanctionsNow Act now for Palestine – rescue the Occupied Territories Bill www.trocaire.org/petitions/ac...
