“Palestine will be your graveyard, Jews,” said the audio recording, described as being by Abu Bakr al-Baghdadi.
It said air strikes by Russia and a US-led coalition had failed to weaken it.
“Be confident that God will grant victory to those who worship him, and hear the good news that our state is doing well. The more intense the war against it, the purer it becomes and the tougher it gets,” said the message.
It slammed Saudi Arabia’s efforts to set up a coalition of Muslim nations to fight his group. “If it was an Islamic coalition, it would have declared itself free from its Jewish and Crusader lords and made the killing the Jews and the liberation of Palestine its goal,” the message said.
The authenticity of the message, posted on Saturday (December 26) on Twitter accounts that have published ISIL statements in the past, could not be verified.
The last such online public message said to be by Baghdadi was posted in May, and he has been reported injured or killed several times in fighting.
