Know why Abu Bakr al-Baghdadi made his presence after 5 years

The Islamic State group's elusive chief Abu Bakr al-Baghdadi has purportedly appeared for the first time in five years in a propaganda video released Monday by the jihadist organisation.
It is unclear when the footage was filmed, but the man said to be Baghdadi referred to last week's deadly attack in Sri Lanka and to the months-long fight for IS's final bastion Baghouz, which ended in March.
"The battle for Baghouz is over," he said, sitting cross-legged on a cushion and addressing three men whose faces have been blurred.
"God ordered us to wage 'jihad.' He did not order us to win," he said.
