美国总统拜登将会在新一轮对乌克兰的援助当中，授权美国政府向乌克兰提供集束炸弹。请看本报昨日的评论：

This past Friday, the White House announced U.S. President Joe Biden’s decision to provide Ukraine with cluster munitions to be used against Russian troops.

This is a clear sign of Ukraine’s long-anticipated spring counteroffensive not going well at all. The tug-of-war on the far-stretching frontline has not delivered any coveted results since the start of the counteroffensive.

评论中提到的cluster muni-tions就是“集束炸弹” ，集束炸弹是是将小型炸弹集合成一个炸弹的形态，在与一般炸弹同样大小的弹体中，装入由数个到数百个的子炸弹，发射后在空中分解，子炸弹散布到广范的地面造成区域性杀伤。
