The Islamic State in Iraq and Syria (ISIS) claimed Friday that an American female hostage being held by the group is dead. The group said 26-year-old Kayla Mueller, a humanitarian aide worker, was killed when a Jordanian air strike hit the building in Syria where she was being held hostage, the SITE Intelligence Group reported.

ISIS said on Twitter that Mueller was buried under the rubble of a building near Raqqa, the group’s de facto capital. “The failed Jordanian aircraft killed an American female hostage,” the message said. “No mujahid was injured in the bombardment and all praise is due to Allah.”

A State Department spokeswoman said the U.S. was investigating the claim but could not confirm them.

“We are obviously deeply concerned by these reports,” National Security Council spokesperson Bernadette Meehan told Business Insider. “We have not at this time seen any evidence that corroborates ISIL’s claim.”

Mueller, a native of Prescott, Arizona, was captured in August 2013 after leaving a Doctors Without Borders hospital in Aleppo, Syria. She is the last known American hostage being held by ISIS.

If the reports turn out to be true, Joint Special Operations Command (JSOC) will likely step up its attacks against the group as they will no longer pose danger to any Americans. Some plans to strike at the group until this point were rejected on the grounds “these things would be too risky to Kayla” said a military official interviewed by Foreign Policy magazine, on condition of anonymity.

The terror group demanded a ransom of more than $6 million in exchange for her freedom, according to The Daily Beast.

Jordan stepped up its own attacks last week after the video announcement by ISIS that it had executed a Jordanian pilot being held hostage by burning him alive in a cage. Amman has since intensified its bombing raids daily in retaliation against the group.

Jordan vowed to chased the Islamic State (ISIS) “wherever they are” in Iraq as well as in Syria while President Barack Obama is afraid to be more aggressive in the face of Congressional ambivalence.

Following Thursday’s raids by Jordan that hit ISIS training centers and weapons storage sites, Foreign Minister Nasser Judeh told Fox News:

We said we are going to take this all the way, we are going to go after them wherever they are and we’re doing that.They’re in Iraq and they are in Syria and therefore you have to target them wherever they are.

U.S. military aircraft provided intelligence, surveillance and reconnaissance to Jordan.

Jordan has a stronger reason than the United Starts to attack ISIS because the terrorist organization controls parts of two countries on Amman’s borders, and Kong Abdullah does not have to deal with the Constitution, Congress and leftist media. However, the ISIS has been a golden opportunity for President Obama to show the world that the United States still is a world leader.

The U.S. Air Force has joined the strike force. That helps Obama “spread the blame” but he also will to spread the credit when ISIS finally is defeated.

Most Americans favor the U.S. Air Force’s bombing of ISIS targets, and Obama has the back of the Western world, shocked by ISIS barbarity. The ISIS is an easier target than a country with established leaders, such as Syrian president  Bashar al-Assad, but Obama reflects the timidity of an American that has lost its confidence.

Previous presidents have launched military attacks on Serbia, Panama, Grenada, and even the Korean War was carried out without Congressional approval. Obama authorized bombing Libya without asking Congress.

Obama has not relied on his presidential power to  bomb the ISIS to smithereens.

Instead, he has been leaning on previous authorization from Congress to support the American participation in the war on terror.

Despite polls that show backing for U.S. bombing missions against ISIS, Americans are paralyzed by dumb, costly and useless wars, dating back to the war in Vietnam and including the supposed “defeat” of terror in Iraq and Afghanistan.

President Obama is prepared to ask Congress for specific authority to bomb the ISIS, but Congress is doing a good of talking. Wimpy Democrats want a time frame that would place a deadline so that military operations won’t drag on like previous wars.

Republican House Speaker John Boehner put the onus on the president to convince the American people. He said Thursday:

His actions are going to be an important part of trying for us to get the votes to actually pass an authorization. This is not going to be an easy lift.

Democrats are hesitant and want any authorization to be limited for three years, while most  Republicans want a broader authorization.

Republican Sen. John McCain said Thursday, “Overall, there’s still no strategy from this administration as to how to combat ISIS.”

Secretary of Defense nominee Ashton Carter told McCain at a Senate hearing on Wednesday that he “absolutely” believes the U.S. needs an ISIS strategy, but he disappointed McCain when asked for specifics.

“I think the strategy connects ends and means…to strengthen” Iraq’s security forces…and to try to build the forces to keep them defeated” in Syria, he said.

McCain shot back, “Well, it doesn’t sound like a strategy to me.”

This video was released by the Hashemite Kingdom of Jordan showing the preparation for the aerial attack on ISIS troops, in revenge for brutal murder of the Jordanian pilot.

Note the strategic placement of women in the Jordanian video (and on the fighter squad), preparing the bombs that will be dropped on the ISIS terrorists.

It is generally understood that Islamic terrorists believe that if they are killed by women they don’t go to heaven or get their 72 virgins.

The West has a lot to learn from the Jordanians when it comes to fighting terrorism.

Jordanian pilots honored their dead wing man Thursday in a flyby over his hometown as they returned from an unnamed “mission,” Jordan state-run television reported.

King Abdullah II was visiting the pilot’s family in Karak also on Thursday, just two days after the Islamic State of Iraq and Syria (ISIS) terror group released the barbaric video showing the captured pilot being burned alive in a cage.

Jordan’s military vowed to take full revenge on the group. The force is participating in the U.S.-led coalition against ISIS.

The Hashemite monarch asked the Obama administration earlier this week for more “sophisticated air-to-ground weaponry, ground-to-ground weaponry, weapons like anti-tank [and] spare parts,” said Senate Armed Services Committee (SASC) Chairman Senator John McCain. Abdullah II managed to submit his request just prior cutting his visit short and flying back to Amman to deal with the murder of his air force pilot.

The senator told media that committee members from both sides of the aisle agreed to sign a letter to President Barack Obama to fast-track deliveries. He added that if the administration did not act immediately in response to the letter, “which every member is going to sign on this committee, we will then introduce legislation direct to the floor.”

Media reports in Arab and Kurdish news outlets reported overnight Wednesday that Jordanian Air Force fighter pilots struck dozens of ISIS fighters in Mosul, Iraq. An unconfirmed report claimed an ISIS commander for the Ninveh area, Abu Obeidah El Tunisi, was killed in the air strike.

Jordan threatened to avenge the death of its pilot at the hands of ISIS; on Wednesday two imprisoned Al Qaeda terrorists were hanged at dawn. Both were on death row and awaiting execution for multiple murders.

Jordan renewed bombing of suspected Islamic State (ISIS) sites in Syria Thursday, two days after the terrorist organization burned alive a captured Jordanian pilot alive.

King Abdullah has asked the Obama administration for more weapons earlier this week before rushing back to Jordan after the barbaric murder.

He spoke with several U.S. Congressmen in Washington and asked them to break the red tape slowing up delivery of weapons, specifically “more sophisticated air-to-ground weaponry, ground-to-ground weaponry, weapons like anti-tank [and] spare parts,” according to Senate Armed Services Committee (SASC) Chairman Sen. John McCain.

He added that committee members from both the Republican Democratic parties agreed to sign a letter to President Barack Obama to fast-track deliveries.

“If the administration doesn’t act right away in response to this letter, which every member is going to sign on this committee, we will then introduce legislation direct to the floor,” according to McCain.

Prime Minister Binyamin Netanyahu sent his condolences Wednesday to King Abdullah II and to the people of Jordan “for the grisly murder of the air force pilot of the Jordanian air force.”

Netanyahu was referring to Tuesday’s release of a new execution video by the Islamic State in Iraq and Syria (ISIS) terrorist group, showing the January 3rd death of Jordanian air force pilot Muath al-Kasaesbeh. The group killed the pilot by burning him alive in a metal cage.

Egyptian President Abdel Fattah el-Sisi also strongly condemned the murder, calling ISIS a “savage, cowardly organization that violates all heavenly doctrines,” the MENA state news agency reported, and also confirmed Egypt’s support for Jordan.

El-Sisi added that the international community “needs to unite to fight terrorism in all its forms and to confront the terrorist groups that use Islamic slogans, even though religion has nothing to do with their actions.”

Netanyahu spoke about the murder while visiting the IDF Hermon Brigade base Wednesday for a briefing by Deputy Chief of Staff Maj.-Gen. Yair Golan and GOC Northern Command Maj.-Gen. Aviv Kochavi. Netanyahu also met with local council chairs from the area.

“In the Islamic State of ISIS they burn people alive,” the prime minister commented. “In the Islamic State of Tehran, they hang them from cranes in the public squares. Both are motivated by an extreme ideology of militant Islamic terrorism that has a cruelty that is unbounded.”

Netanyahu also reiterated that although world leaders are “racing to forge a deal” that would enable Iran to have nuclear weapons, “Israel will oppose this deal, which is dangerous to us, dangerous to the region, and dangerous to the world.

“But the greatest danger to the future and the security of the world is that this extremism will be backed up by nuclear weapons,” he added. “This is something everyone must oppose.”

Arab and Kurdish reports say the Jordanian Air Force struck in Mosul, Iraq, killing dozens of ISIS terrorists, perhaps as many as 56, including an ISIS commander for the Ninveh area, Abu Obeidah El Tunisi.

Other reports add that the Jordanian troops and armor are massing on the Syrian and Iraqi borders.

These report are still unverified at this point.

Jordan has threatened to take extreme measures against ISIS for the obscene murder of the Jordanian pilot. On Wednesday morning, Jordan executed two ISIS terrorists in response to the murder of the pilot.
