The U.K. canceled its first deportation flight to Rwanda after an eleventh-hour intervention by the European Court of Human Rights, which ruled there is ¡°a real risk of irreversible harm¡± to the asylum-seekers involved.

The flight had been scheduled to leave Tuesday evening. Home Secretary Priti Patel vowed to push on with the flagship policy.

¡°I have always said this policy will not be easy to deliver and am disappointed that legal challenge and last-minute claims have meant the flight was unable to depart,¡± Patel said in a statement.
