"oppressive someone" - Translation from English to Arabic

It would have been much more appropriate for the Secretary-General, as someone in a global position, to support the Iranian people's human rights and to condemn the nature of such oppressive sanctions against them.
وكان من الأنسب للأمين العام بوصفه شخصا يشغل منصبا عالميا أن يدعم حقوق الإنسان الخاصة بالشعب الإيراني، ويدين الطبيعة القمعية لهذه الجزاءات المفروضة عليه.
