The authorities in Nigeria's RiverState where more than thirty people died in a crush on Saturday say a local government committee will closely study the circumstances behind the tragedy.

BBC双语把这里的crush翻译为“踩踏”，但是我查字典看到crush的动词是“压扁，压碎，镇压”，名词比较接近的只有“拥挤的人群”的意思，并没有“踩踏”的含义，而且就算取动词的“压扁”含义，这里也应该使用动名词crushing才对，请问该如何理解？
