Islamic State says audio tape is of leader Baghdadi The Islamic State group has released an audio recording it said is of its chief Abu Bakr al-Baghdadi, days after an air strike on jihadist leaders in Iraq sparked rumours he had been wounded or killed. In the 17-minute message, the man purported to be Baghdadi made no direct reference to the alleged strike against Isis leadership but mentioned developments that have occurred since. In the message the man calls for attacks in Saudi Arabia, said the Caliphate was expanding across the Arab world and called for "volcanoes of jihad" across the globe. The speech also said that a US-led military campaign against Isis in Syria and Iraq was failing. The recording - which was carried on jihadist websites - appeared authentic, and the man's voice appeared to correspond with previous recordings released by the group.
