Australia's prime minister has welcomed the death of Islamic State leader Abu Bakr al-Baghdadi but says it does not end the campaign "to defeat this terrorist group and the extremism it embodies."

Prime Minister Scott Morrison says in a statement the death is "a significant blow" to the Islamic State group and "another important step in preventing its revitalization."

Morrison says al-Baghdadi inspired or directed cowardly attacks by Islamic State group followers against "innocent civilians around the world, some of whom were Australian."

The Prescott, Arizona parents of slain American hostage Kayla Mueller say they have mixed emotions about the death of Islamic State leader Abu Bakr al-Baghdadi.

Their daughter was a humanitarian aid worker who was kidnapped and taken hostage in August 2013 after leaving a Doctors Without Borders hospital in Aleppo, Syria.

Mueller's death was reported in February 2015 and U.S. intelligence officials told her family four months later that she was raped repeatedly by al-Baghdadi.

Carl Mueller told The Arizona Republic on Sunday that al-Baghdadi "either killed her or he was complicit in her murder."

Marsha Mueller says she wants to know what truly happened to her daughter "and what aren't we being told."

Kayla Mueller's body has yet to be recovered.

House Speaker Nancy Pelosi is criticizing the White House for failing to notify congressional leaders before the U.S. raid in Syria that President Donald Trump says killed the leader of the Islamic State group.

She notes that the U.S. let Russia know the raid was in the works.

Trump said U.S. military helicopters flew over territory controlled by Russian and Syrian forces before landing at Abu Bakr al-Baghdadi's compound. He also said he kept lawmakers out of the loop because he was fearful of leaks.

Pelosi says the Trump administration must brief Congress on the operation and on the administration's overall strategy for the Mideast.

Before the 2011 raid in Pakistan that killed al-Qaida leader Osama bin Laden, the Obama administration did give advance word to the top two Democrats and Republicans in the House and Senate as well as the four leaders of the congressional intelligence committees.

President Donald Trump says European nations have been a "tremendous disappointment" in what he says is their unwillingness to bring home captured Islamic State fighters from their home countries.

He's renewing his threat to release imprisoned fighters at their borders.

Trump has repeatedly and publicly pressed Europe to take back their large numbers of imprisoned fighters, but that push has been met by some resistance.

The U.S. has said it wants to lead by example and several captured fighters have been returned to America for prosecution.

The Russian Defence Ministry is expressing skepticism about President Donald Trump's announcement that Islamic State leader Abu Bakr al-Baghdadi has been killed in a U.S. raid in Syria.

The ministry says in a statement that there were no recorded airstrikes in the Idlib zone on Saturday where the operation is said to have taken place.

Trump said U.S. military helicopters flew over territory controlled by Russian and Syrian forces before landing at al-Baghdadi's compound.

The Russian statement says the ministry is unaware of "any alleged assistance to the passage of American aircraft into the airspace of the Idlib de-escalation zone during this operation."

It also suggested that al-Baghdadi's presence in that area would be unlikely because the territory is controlled either by the Syrian government or by an al-Qaeda affiliate that is an IS rival.

Vice-President Mike Pence is disclosing more details about the U.S. military raid that killed Islamic State leader Abu Bakr al-Baghdadi in Syria.

Pence says that by Thursday afternoon, he and President Donald Trump learned that there was "a high probability" that al-Baghdadi would be at his compound in Syria's Idlib province.

Pence tells CBS' "Face the Nation" that Trump directed commanders to come up with military options and present them to him on Friday morning.

Pence says that by Saturday morning, "we received the actionable intelligence" that allowed the operation that Trump had approved to go ahead.

And it was on Sunday morning when Trump told the nation that the raid had resulted in al-Baghdadi's death.

The head of the foreign affairs committee in Russia's upper house of parliament says the death of Islamic State leader Abu Bakr al-Baghdadi would be welcome news, but he's playing down its possible impact in the fight against terrorism.

Konstantin Kosachev is pointing out that President Donald Trump's announcement Sunday in Washington that al-Baghdadi was killed in a U.S. military raid in Syria isn't the first time the leader's death has been reported.

Kosachev says "countering terrorism is a much more difficult task than the physical destruction of its leaders, even the most implacable."

Some information is emerging about how the United States might have been able to track Islamic State leader Abu Bakr al-Baghdadi.

A senior Iraqi intelligence official says that a few months ago, an Iraqi aide to al-Baghdadi was killed in western Iraq by a U.S. airstrike. The official says the aide's wife was arrested in the operation and handed over by the Americans to Iraqi authorities.

The official says the wife ended up being a key source of information on al-Baghdadi's whereabouts and that through her, the Iraqis ultimately were able to pass along to the United States co-ordinates on al-Baghdadi.

A second Iraqi security official says al-Baghdadi's brother-in-law was recently arrested by the Iraqis and also helped with information about Abu Bakr's whereabouts

The officials weren't authorized to publicly discuss intelligence operations and spoke on condition of anonymity.

Trump says that he watched much of the mission unfold from the White House Situation Room on Saturday night.

Trump says at the White House on Sunday that the U.S. had al-Baghdadi under surveillance for several weeks. He says that during the raid, U.S. forces flew low and fast, and were met with gunfire at points.

Abu Bakr al-Baghdadi, the shadowy leader of the Islamic State group, had a $25 million U.S. bounty on his head.

He鈥檇 kept a low public profile in recent years, releasing only sporadic audio recordings. In a recording just last month, he called on members of the extremist group to do all they could to free IS detainees and women held in jails and camps.

That purported audio was his first public statement since last April, when he appeared in a video for the first time in five years.

The video included images of the IS leader sitting in a white room with three others. He praised Easter Day bombings that killed more than 250 people and called on militants to be a 鈥渢horn鈥 against their enemies.
