英语翻译I fully sanction the continued supply of international f

英语翻译
I fully sanction the continued supply of international funding from develped nations to developing countries as there have been numerous accounts where this aid has achieved real results.
请解释一下accounts在这里的具体含义以及where在这里的语法含义,
了解了account在这里作报道讲，那么where是指代in which 还是at which呢？也就是说关于“在这些报道中”的介词准确的来说应该使用in还是at呢？最好能提供例句讲解，
