The mother of kidnapped New Hampshire journalist James Foley says her son gave his life trying to expose the world to the suffering of the Syrian people.
"We have never been prouder of our son Jim," said Diane Foley, in a statement posted on the "Free James Foley" Facebook page.
A video by Islamic State militants Tuesday purported to show the cold-blooded execution of Foley as retribution for U.S. airstrikes in Iraq.
Governor Maggie Hassan released a statement Tuesday night on Foley's death, calling him a "talented and fearless photojournalist."
"The appalling actions of ISIS are a crime against humanity and the values that we all hold dear. I join all Granite Staters and people around the world in mourning the tragic loss of James Foley, and our thoughts and prayers are with his family and loved ones.”
In a statement, Congresswoman Carol Shea-Porter also said her thoughts and prayers are with the family.
"I remember Jim Foley as a child and I will not allow evil to change the way I remember him. I will always choose to remember his goodness, his life, and his great family. "
Foley, a 40-year-old freelance journalist from Rochester, went missing nearly two years ago in northern Syria while on assignment for Agence France-Press and the Boston-based media company GlobalPost. The car he was riding in was stopped by four militants in a contested battle zone that both Sunni rebel fighters and government forces were trying to control. He had not been heard from since.
White House National Security Council spokeswoman Caitlin Hayden said the administration has seen the video and that the intelligence community is working as quickly as possible to determine if it is authentic.
"If genuine, we are appalled by the brutal murder of an innocent American journalist and we express our deepest condolences to his family and friends," Hayden said in a statement.
In her statement, Diane Foley pleaded with her son's kidnappers to release the remaining hostages.
"Like Jim, they are innocents. They have no control over American government policy in Iraq, Syria or anywhere in the world," she said. "We thank Jim for all the joy he gave us. He was an extraordinary son, brother, journalist and person. Please respect our privacy in the days ahead as we mourn and cherish Jim."
Philip Balboni, GlobalPost CEO and co-founder, said the company had been informed that the FBI is in the process of evaluating the video to determine whether it was authentic. "We ask for your prayers for Jim and his family," he said.
Several senior U.S. officials with direct knowledge of the situation said the Islamic State very recently threatened to kill Foley to avenge the crushing airstrikes over the last two weeks against militants advancing on Mount Sinjar, the Mosul dam and the Kurdish capital of Irbil.
Both areas are in northern Iraq, which has become a key front for the Islamic State as its fighters travel to and from Syria.
The officials spoke on condition of anonymity because they were not authorized to discuss the hostage situation by name.
Since Aug. 8, the U.S. military has struck more than 70 Islamic State targets — including security checkpoints, vehicles and weapons caches. It's not clear how many militants have been killed in the strikes, although it's likely that some were.
The Islamic State militant group is so ruthless in its attacks against all people they consider heretics or infidels that it has been disowned by al-Qaida's leaders. In seeking to impose its harsh interpretation of Islamic law in the lands it is trying to control, the extremists have slain soldiers and civilians alike in horrifying executions — including mounting the decapitated heads of some of its victims on spikes.
The group is the heir apparent of the militancy known as al-Qaida in Iraq, which beheaded many of its victims, including Americans businessman Nicholas Berg in 2004.
