WASHINGTON: Fugitive leader of the militant Islamic State (IS) group Abu Bakr alBaghdadi died `whimpering and crying` in a raid by US special forces in northwest Syria, President Donald Trump announced on Sunday, in what he called a major victory over the terrorist outfit.

Baghdadi killed himself during the raid by detonating a suicide vest after fleeing into a dead-end tunnel, Trump said ina televised address from the White House.

He was positively identifiedby DNA tests 15 minutes after he died,the president said.

`He was a sick and depraved man and now he`s gone,` said Trump, adding that capturing or killing Baghdadi had been the top national security priority for his administration.

The death of Baghdadi is a severe blow to IS, which has been in disarray and has no declared successor as leader yet. But the group has in the past proved resilient, continuing to mount or inspire attacksin the region and beyond despite losing most of its territory in recent years.

Trump said `many` of Baghdadi`s people were killed in the raid and added that in blowing himself up, he also killed three ofhis children.US forces suffered no personnel losses, he said. He also thanked Russia, Turkey, Syria andIragfor their support.

Turkey said it was proud to have helped `bring a notorious terrorist to justice` and Israel`s Prime Minister Benjamin Netanyahu congratulated Trump on an `impressive achievement`.

Russia`s response was muted, however, with the defence ministry in Moscow saying merely that it had no reliable information on the US raid.

Baghdadi had long been sought by the United States as head of a militant group that at one pointcontrolled large areas of Syria and Iraq, where it declared a `caliphate`.

IS carried out atrocitiesagainst religious minorities and attacks on five continents that horrified mainstream Muslims.

`The thug who tried so hard to intimidate others spent his last moments in utter fear, panic and dread, terrified of the American forces coming down on him,` Trump said.

`He reached the end of the tunnel as our dogs chased him down. He ignited his vest, killing himself and his three children. His body was mutilated by the blasts. The tunnel had caved on him,` Trump added.

`He died ... whimpering and crying and screaming.

Sound of planes In the hours before Trump`sannouncement, sources in the region had described the raid on a compound in the village of Barisha, in Idlib province bordering Turkey, in the early hours of Sunday.

`We woke up to the sound of planes, we went out and saw (forces) in front of us carrying weapons. `Get on the ground, get on the ground!` (they said) so we went down,` one local resident told Reuters TV.

`They handcuffed us and put us to the side. (They asked) `How do you know this man?` We said we don`t know him, we would see people coming and going but we never interacted with them. So they said, `you are safe, stay to the side`.

Iraqi state television broadcast night-time footage of an explosion and daytime images of a crater in the ground and what it said was the aftermath of the raid, including torn and blood-stained clothes.

Iraq`s military said later in a statement that its intelligence services had located Baghdadi`s whereabouts and had passed the information to the United States.

Trump said eight helicopters carried the US special forces troops to the compound where Baghdadi was hiding, where they were met with gunfire before blasting their way in through the walls to avoid a booby-trapped main door.

The US forces spent around two hours in the compound, he said, adding that they had taken away `sensitive information` relating to IS.

Russia `treated us great` by opening up airspace it controlled for the raid and Kurdish allies gave some helpful information, according to Trump.

The president said he watched the operation unfold in the Situation Room of the White House, with Vice President MikePence, Defence Secretary Mark Esper and the joint military chiefs. He added that Russia had not been aware of the nature of the US mission.

Millions of people At the height of its power, IS ruled over millions of people in territory running from northern Syria through towns and villages along the Tigris and Euphrates valleys to the outskirts of the Iraqi capital Baghdad.

Thousands of civilians were killed by the group as it mounted what the United Nations called a genocidal campaign against Iraq`s Yazidi minority.

It also caused worldwide revulsion by beheading foreign nationals from countries including the United States, Britain and Japan.

IS claimed responsibility for or inspire d attacksin dozens ofcitiesincluding Paris, Nice, Orlando, Manchester, London and Berlin, and in nearby Turkey, Iran, Saudi Arabia and Egypt. But in 2017 the group lost control of Mosul in Iraq and Raqqa in Syria, and quickly thereafter almost all of its territory, turning Baghdadi into a fugitive.-Reuters
