Actually, around 40 other public observers from across Europe had the same access granted and then revoked. Many of them were from other countries, happy not to need to travel during the pandemic, and they woke up the morning of the first day to discover their access revoked.
So you’re saying the humanitarian problem is even bigger than just Amnesty International. Not even other international observers can see whether the trial is fair.
This is truly alarming, to a much bigger scale, in this case.
