A video released by the Islamic State group on Friday appears to show the beheading of British aid worker Alan Henning, the Associated Press reports. In the clip, the militants threaten to kill another hostage they identify as American Peter Kassig.
Alan Henning, a 47-year-old taxi driver from Eccles, was kidnapped in December after crossing into Syria with an aid convoy. Henning's wife, Barbara, had pleaded with the militants not to kill her husband. "He went to Syria to help his Muslim friends deliver much needed aid," she said in a statement released on Sept. 23.
Catrin Nye, a BBC reporter who had filmed with Henning, described the Brit as "kind and funny."
A video released on Friday appears to show the killing of Alan Henning by militants of the Islamic State.
Friday's video identifies the other hostage as Peter Kassig, a U.S. citizen. It was not immediately clear when the man was kidnapped. Two U.S. officials confirmed to the Associated Press that Kassig is being held by Islamic State militants.
CNN described CNN described Kassig in 2012 as a former U.S. soldier turned aid worker, who helped wounded Syrians at a hospital in Lebanon. According to a 2013 Time magazine report, Kassig later started his own aid group in Syria and Lebanon, called Special Emergency Response and Assistance. At the time, SERA focused on providing refugees with medical and other supplies.
In a statement issued later Friday, British Prime Minister David Cameron said of Henning's killing, "The fact that he was taken hostage when trying to help others and now murdered demonstrates that there are no limits to the depravity of these ... terrorists."
U.S. President Barack Obama condemned the "brutal murder," saying "Standing together with our UK friends and allies, we will work to bring the perpetrators of Alan's murder -- as well as the murders of Jim Foley, Steven Sotloff and David Haines -- to justice," and, "we will continue taking decisive action to degrade and ultimately destroy ISIL."

CAIRO (AP) — An Internet video released Friday purports to show an Islamic State group fighter beheading British hostage Alan Henning, the fourth such killing carried out by the extremist group now targeted in U.S.-led airstrikes.
The video mirrored other beheading videos shot by the Islamic State group, which now holds territory along the border of Syria and Iraq, and ended with a militant threatening a man they identified as an American named Peter Kassig.
"Obama, you have started your aerial bombardment of Shams (Syria), which keeps on striking our people, so it is only right that we continue to strike the neck of your people," the masked militant in the video said.
Two U.S. officials, who spoke on condition of anonymity out of concerns of not having permission to release the information, confirmed that Kassig was being held by Islamic State militants. The officials declined to elaborate.
The Associated Press could not immediately verify the video's authenticity, though it was released in the same manner as other Islamic State group videos and the masked militant sounded similar to the one who carried out the other slayings.
In a statement, the British Foreign Office said it was working to verify the video.
"If true, this is a further disgusting murder," the statement read. "We are offering the family every support possible; they ask to be left alone at this time."
Britain has been supporting U.S. military efforts against the Islamic State group by using British forces to help with logistics and intelligence gathering, as well as recently taking part in airstrikes in Iraq. The Internet video released Friday begins with a news clip announcing British strikes against the Islamic State group.
British Prime Minister David Cameron said Henning's apparent slaying showed "how barbaric and repulsive these terrorists are."
"Alan had gone to Syria to help get aid to people of all faiths in their hour of need," Cameron said in a statement. "The fact that he was taken hostage when trying to help others and now murdered demonstrates that there are no limits to the depravity of these ... terrorists.
"We will do all we can to hunt down these murderers and bring them to justice."
President Barack Obama's counterterrorism adviser, Lisa Monaco, said the U.S. had seen the video and was evaluating it.
Later, Obama said the United States strongly condemned Henning's "brutal murder." He said the U.S., along with Britain and other allies, will "work to bring the perpetrators of Alan's murder" to justice and will continue to "taking decisive action to degrade and ultimately destroy" the Islamic State group.
French President Francois Hollande said he is "outraged by the heinous crime."
"This crime like previous ones will not be unpunished. France will continue to lend support to the people and authorities of Iraq in their fight against terrorism," Hollande said in a statement.
This is the fourth such video released by the Islamic State group. The full beheadings are not shown in the videos, but the British-accented, English-speaking militant holds a long knife and appears to begin cutting his victims, who include American reporter James Foley, American-Israeli journalist Steven Sotloff, British aid worker David Haines and now Henning.
FBI Director James Comey has said American officials believe they know the identity of the masked militant, though he's declined to name the man or reveal his nationality.
Kassig, a 26 year-old American now threatened by the Islamic State group, enlisted in the Army in 2004, and became a Ranger, ultimately serving in the 75th Ranger Regiment, an Army special operations unit.
According to his military record, Kassig trained at Fort Benning, Georgia in 2006, and deployed to Iraq from April to July 2007. He was medically discharged at the rank of private first class in September 2007. His home of record at the time of his enlistment was Indianapolis, Indiana.
His parents, Ed and Paula Kassig, issued a statement through a media relations firm, asking for the world to pray for their son.
"The Kassig family extends our concern for the family of Alan Henning. We have read about his work and his generous character with great respect and admiration," the statement said. "We ask everyone around the world to pray for the Henning family, for our son, and for the release of all innocent people being held hostage in the Middle East and around the globe."
The family said Kassig had been working for the relief organization SERA when he was captured on Oct. 1, 2013 on his way to Deir Ezzour in eastern Syria. He converted to Islam while in captivity and the family has heard from former hostages that his faith has provided him comfort.
Henning, 47, nicknamed "Gadget," had joined an aid convoy and was taken captive on Dec. 26, shortly after crossing the border between Turkey and Syria. Earlier this week, Henning's wife Barbara Henning asked the militants in a televised plea: "Please release him. We need him back home."
Dozens of Muslim leaders in Britain have urged the Islamic State group to release Henning. His wife had said she had been given hope by "the outcry across the world" over her husband's imprisonment.
Mohammed Shafiq, chief executive of the Ramadhan Foundation, a Muslim charity, called Henning "a British hero."
His "barbaric killing is an attack against all decent people around the world," Shafiq said.
The Islamic State group has its roots in al-Qaida's Iraqi affiliate but was expelled from the global terror network over its brutal tactics and refusal to obey orders to confine its activities to Iraq. It became even more extreme amid the bloody 3-year civil war in neighboring Syria, growing stronger to the point of being able to launch a lightning offensive across much of northern Iraq, routing security forces there and shooting down an Iraqi helicopter on Friday. The group has become known for filming and releasing footage of mass shootings it conducts, as well as beheading opponents and targeting religious and ethnic minorities in the areas it attacks.
The extremist group has been widely denounced by mainstream Muslim authorities.
Other foreigners are believed held by the Islamic State group. On Friday, the father of John Cantlie, a British photojournalist held by the group, appealed for his release in a video, saying he was a friend of Syria.
