(CNN) ISIS confirmed the death of former leader Abu Bakr al-Baghdadi and named his replacement in an audio message on Thursday.

In the recording, published on the terrorist group's media wing al-Furqan, ISIS announced its new leader as Abu Ibrahim al-Hashimi al-Qurashi.

Baghdadi died during an American commando raid on his compound in northern Syria over the weekend.

Thursday's message was voiced by ISIS' new spokesman Abu Hamza al-Qarshi. He replaces former spokesman Abu Hasan al-Muhajir, who was killed by US forces near Jarablus in northern Syria, a senior State Department official said Monday.

"America, do not be happy with the killing of Sheikh al-Baghdadi," the new spokesman said in the recording. "Do you not realize that the State today is not only on the doorstep of Europe and in the center of Africa, it is staying and expanding from the east to the west."
