As 'caliphate' ends, where is ISIS leader Abu Bakr al-Baghdadi?
The world's most wanted man who has so far eluded capture, Islamic State in Iraq and Syria (ISIS) group chief Abu Bakr al-Baghdadi has seen his "caliphate" crumble and its last shred of territory in Syria evaporate on Saturday (March 23).
After declaring himself caliph in 2014, Baghdadi held sway over seven million people across swathes of Syria and Iraq, where ISIS implemented its brutal version of Islamic law.
But that land has been whittled down to disjointed sleeper cells by years of fighting, including a ferocious bombing campaign by the US-led coalition.
Reclusive even when ISIS was at the peak of its power, the 47-year-old Iraqi, who suffers from diabetes, has been rumoured to have been wounded or killed several times in the past. And his whereabouts have never been confirmed.
So, with his proto-state gone and a US$25 million (S$33.82 million) US bounty on his head, where is Baghdadi?
"He only has three companions: his older brother Jumaa, his driver and bodyguard Abdullatif al-Jubury, whom he has known since childhood, and his courier Saud al-Kurdi," said Mr Hisham al-Hashemi, an Iraqi specialist in ISIS.
Mr Hashemi said the quartet is likely laying low somewhere in Syria's vast Badia desert, which stretches from the eastern border with Iraq to the sweeping province of Homs.
That is where his son Hudhayfa al-Badri was reportedly killed in July by three Russian guided missiles, he added.
Nicknamed "The Ghost", he has not appeared in public since he delivered a sermon at Mosul's famed Al-Nuri mosque in 2014 declaring himself "caliph".
His last voice recording to his supporters was released in August, eight months after Iraq announced it had defeated ISIS and as US-backed forces closed in next door in Syria.
But as the Kurdish-led Syrian Democratic Forces pressed the "final battle" against ISIS's last sliver of territory, a spokesman for the US-backed group said the elusive leader was likely not there.
"We do not think he is in Syria," Mustafa Bali told AFP, without elaborating.
But some of those who fled Baghuz in the dying days of the caliphate, claimed they had been ordered to leave by Baghdadi.
"Had the caliph not ordered it, we would not have left," one woman told AFP in late February, referring to Baghdadi, who was not believed to have been among the extremists in their last holdout.
Keeping a low profile - in contrast to slain Al-Qaeda leader Osama bin Laden - has helped Baghdadi survive for years.
Born Ibrahim Awad al-Badri in 1971, the passionate football fan came from modest beginnings in Samarra, north of Baghdad.
His high school results were not good enough for law school and his poor eyesight prevented him from joining the army, so he moved to the Baghdad district of Tobchi to study Islam.
"He had a vision, early on, of where he wanted to go and what kind of organisation he wanted to create," said Ms Sofia Amara, author of a 2017 documentary that unveiled exclusive documents on Baghdadi.
After US-led forces invaded Iraq in 2003, he founded his own insurgent organisation but never carried out major attacks.
When he was arrested and held in a US detention facility in southern Iraq in February 2004, he was still very much a second- or third-tier Islamist.
But it was Camp Bucca - later dubbed "the University of Jihad" - where Baghdadi came of age as a terrorist.
"People there realised that this nobody, this shy guy was an astute strategist," Ms Amara said.
He was released at the end of 2004 for lack of evidence. Iraqi security services arrested him twice subsequently, in 2007 and 2012, but let him go because they did not know who he was.
In 2005, this father of five from two different wives pledged allegiance to Abu Musab al-Zarqawi, the brutal leader of Iraq's Al-Qaeda franchise.
Zarqawi was killed by an American drone strike in 2006, and after his successor was also eliminated, Baghdadi took the helm in 2010.
He revived the Islamic State of Iraq (ISI), expanded into Syria in 2013 and declared independence from Al-Qaeda.
In the following years, Baghdadi's ISIS group captured swathes of territory, set up a brutal system of government, and inspired thousands to join the "caliphate" from abroad.
Baghdadi was raised in a family divided between a religious clan and officers loyal to Saddam's secular Baath party.
Years later, his Islamist group incorporated ex-Baathists, capitalising on the bitterness many officers felt after the American move to dissolve the Iraqi army in 2003.
That gave his leadership the military legitimacy he personally lacked and formed a solid backbone of what was to become ISIS, combining extreme religious propaganda with ferocious guerrilla efficiency.
Uncharismatic and an average orator, Baghdadi was described by his repudiated ex-wife Saja al-Dulaimi, who now lives in Lebanon, as a "normal family man" who was good with children.
He is thought to have had three wives in total, Iraqi Asma al-Kubaysi, Syrian Isra al-Qaysi and another, more recently, from the Gulf.
He has been accused of repeatedly raping girls and women he kept as "sex slaves", including a pre-teen Yazidi girl and US aid worker Kayla Mueller, who was subsequently killed.
