The Islamic State released a taped message on Saturday with a purported speech by it's leader Abu Bakr al-Baghdadi in which he threatened the Jewish State. "We are getting closer to you day by day," said the message. "Do not think that we have forgotten about you." "God caused the Jews of the world to gather in Israel, and the war against them has become easy. It is the obligation of every Muslim to carry out Jihad," "Jews, you will not enjoy in Palestine. God has gathered you in Palestine so that the Mujahadeen can reach you soon and you will hide by the rock and the tree. Palestine will be your graveyard," he said. The audio message said air strikes by Russia and by a US-led coalition had failed to weaken the group."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," Baghdadi added. The authenticity of the message, posted on Saturday on Twitter accounts that have published Islamic State statements in the past, could not be verified. 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.
