 ISIS WARNS GOVERNMENT TO END EVIL ALLIANCE OF AMERICA AGAINST THE ISLAMIC STATE.

US journalist executed by ISIS was Israeli citizen

U.S. confirms authenticity of video issued by Islamic State showing beheading of Miami-born journalist Steven Sotloff • 

ISIS warns governments to end "evil alliance of America against the Islamic State" • President Barack Obama: Justice will be served.

Steven Sotloff, the American journalist whose beheading features in a gruesome video issued Tuesday by the Islamic State group, was an Israeli citizen who had lived and studied in Israel.

Sotloff, the grandson of Holocaust survivors who immigrated to Florida, came to Israel in 2008 to pursue an undergraduate degree at the Interdisciplinary Center in Herzliya. 

His Israeli citizenship and Jewishness were suppressed by the media while he was alive in an effort to protect him from his Islamist captors.

Sotloff, 31, was captured by ISIS terrorists in northern Syria last August while working as a freelance journalist and covering the civil war ravaging Syria. 

His captors were apparently not aware of his Israeli citizenship or his Jewish faith.

"We refused to acknowledge any relationship with him in case it was dangerous for him," said Avi Hoffman, editor of the Jerusalem Report magazine, which had published Sotloff's work.

The Israeli newspaper Yedioth Ahronoth, quoting a former fellow captive, said Sotloff had kept his Judaism a secret from the Islamist insurgents, pretending he was sick when he fasted for the Yom Kippur holiday.

The Islamic State group released the video on Tuesday, two weeks after a similar video was released in which American journalist James Foley was also beheaded.

In the video, a masked figure also issued a threat against a British hostage, named as David Haines, and warned governments to back off "this evil alliance of America against the Islamic State," warning against U.S. airstrikes in Iraq.

U.S. President Barack Obama declared on Wednesday that Americans would not be intimidated by the "horrific" IS tactic. He vowed that "justice will be served" after the U.S. verified the authenticity of the video.

Obama said at a news conference while traveling Wednesday in Estonia that Sotloff's and Foley's deaths only unite Americans. He said Americans would not forget and that the country's reach is long.

In the video, the executioner appeared to be the same British-accented man who appeared in the Aug. 19 video featuring Foley, and it showed a similar desert setting. In both videos, the captives wore orange jumpsuits.

"I'm back, Obama, and I'm back because of your arrogant foreign policy toward the Islamic State, because of your insistence on continuing your bombings and in Amerli, Zumar and the Mosul Dam, despite our serious warnings," the masked man said in the video.

"So just as your missiles continue to strike our people, our knife will continue to strike the necks of your people," he said.

In the video, Sotloff describes himself as "paying the price" with his life for the U.S. intervention in Iraq.

On Tuesday, following the release of the video, the White House said that Obama was sending three top officials -- Secretary of State John Kerry, Defense Secretary Chuck Hagel and counterterrorism adviser Lisa Monaco -- to the Middle East "in the near-term to build a stronger regional partnership" against the Islamic State terrorists.

U.S. officials also said Obama had ordered 350 more U.S. military personnel to protect the large American Embassy in Baghdad, bringing up to about 820 the number of U.S. forces working to bolster diplomatic security in Iraq.

"The president has made clear his commitment to doing whatever is required to provide the necessary security for U.S. personnel and facilities around the world," White House spokesman Josh Earnest said in a statement.

"The request he approved today will allow some previously deployed military personnel to depart Iraq, while at the same time providing a more robust, sustainable security force for our personnel and facilities in Baghdad."

The White House said the additional troops heading to Baghdad would not serve in a combat role.

Pentagon spokesman Rear Admiral John Kirby told reporters that as long as ISIS poses a threat to the Mosul Dam, the United States would continue targeting it.

Asked by a reporter to give clear picture about the situation on the ground at the Mosul Dam and why the United States keeps launching airstrikes at that location, Kirby said: "Because [ISIS] keeps trying to take it back. 

As I said last week, as long as they continue to pose a threat to the facility, we're gonna continue to hit 'em. And we are."

Sotloff's mother, Shirley, appealed last Wednesday for her son's release in a videotaped message to Islamic State's self-proclaimed caliph, Abu Bakr al-Baghdadi.
