请教一个短语的意思
Basayev took credit for attacks that killed hundreds of people, including the Moscow theater siege, and the notorious 2004 Beslan school massacre.
其中take credit for是什么意思，我在字典中查到的是褒义。而在此处明显应该是贬义。如何解释？
参考答案:此处take credit for是为某事负责之意，和thank有异曲同工之妙，如：
You burnt down my house! Thanks for your excellent job, I'm now a
homeless man.
