From the French press. It's confirmed in Wikipedia:
Amnesty's Canadian branch issued a statement expressing regret for among other things the "insufficient context and legal analysis".[137] On 12 August, Amnesty's German branch issued a statement apologizing for aspects of the report's release and its effect,
saying that it would be examined through a process initiated at the international level to determine what went wrong, and condemning its instrumentalization by Russian authorities.[138]
The reaction by the Canadian Chapter was in my opinion absolutely spot on:
Response to Amnesty International’s August 4, 2022, Press Release
Amnesty International Canadian Section (English Speaking) acknowledges and deeply regrets the hurt, anger, and disappointment caused to our Ukrainian colleagues, the Ukrainian community at large, members, and supporters across Canada following the August 4 press release on research conducted on Russian strikes between April and July 2022.
In every conflict situation, Amnesty’s primary focus is the protection of human rights and civilians, particularly those most vulnerable and at risk. Although this was the intention of the research and extended press release, Amnesty International failed on several fronts.
We regret the insufficient context and legal analysis, particularly given the nature of Russia’s aggression. These findings were not communicated with the sensitivity, responsibility, and precision required and expected of Amnesty. We recognize the magnitude and impact of these failings from an institution of our stature, particularly in times of conflict.
The manner in which the International Secretariat conducted this work, engaged with sections internally, and publicly communicated these findings resulted in creating the opposite effect and challenged our core principle of impartiality. We also regret the International Secretariat subsequent communication and response to public and legal critique.
We condemn Russia’s instrumentalization of the press release to justify its illegal aggression. Since the start of the invasion in February, Amnesty International has and continues to categorically condemn Russia’s invasion of Ukraine as an unjustified act of aggression and a grave violation of international law.
Our commitment to investigate the Russian military’s aggression and war crimes against the Ukrainian people is reflected in the extensive research conducted since the beginning of the invasion in February. Amnesty has documented war crimes committed by Russian forces in Ukraine in nearly two dozen outputs—ranging from press releases to a 72-page report.
As a section firmly committed to an equitable and decolonized approach to human rights, we greatly regret the deficiency in the collaboration between our International Secretariat and our AI Ukraine colleagues, which resulted in the resignation of Amnesty Ukraine’s director.
A decolonial approach begins with the principle to do no harm and centering those we are privileged to work with, particularly when they are most impacted and when they tell us that they are in harm’s way. How we work is as important as what we work on—and, in this case, our ways of working from an equity-informed perspective fell unacceptably short.
Several years ago, Amnesty International purposefully decentralized to better listen, respond to, and be led by the voices of human rights defenders on the frontlines. Unfortunately, this press release defaulted to outdated ways of working that centralize knowledge and decision-making while placing local expertise and understanding at the margins. We have done this at considerable risk to our colleagues and rights holders in Ukraine. [...]
