ISIS executes American journalist James Foley

>> Reporter: WELL, KATE, GOOD

MORNING.

JUST A SHORT TIME AGO NOW, THE

BRITISH FOREIGN SECRETARY

WEIGHING IN ON ALL OF THIS,

EXPRESSING A GOOD DEAL OF

CONCERN BECAUSE ON THAT TAPE THE

EXECUTIONER, THE MURDERER OF

JAMES FOLEY, APPEARS TO HAVE A

BRITISH ACCENT.

INTELLIGENCE SERVICES ON BOTH

SIDES OF THE ATLANTIC NOW

WORKING TO TRY AND IDENTIFY HIS

MURDERER, THE FRIENDS AND FAMILY

OF JAMES FOLEY REMEMBERING HIS

LIFE AND HIS CAREER AS A

JOURNALIST.

THE ISIS VIDEO IS SIMPLY TOO

HORRIFIC TO SHOW.

THE MAN BEING EXECUTED BY

BEHEADING IS JAMES FOLEY, A

FREELANCE JOURNALIST KIDNAPPED

IN NORTHWEST SYRIA ON NOVEMBER

22nd, 2012, THANKSGIVING DAY.

ISIS, THE BRUTAL MILITANTS,

RAMPAGING THROUGH SYRIA AND

IRAQ, SAY THEY KILLED FOLEY IN

RETALIATION FOR U.S. MILITARY

OPERATIONS IN IRAQ.

FOLEY, A FREELANCE

PHOTOJOURNALIST FROM NEW

HAMPSHIRE, READS A MESSAGE

DENOUNCING THE U.S. PRESUMABLY

WRITTEN BY HIS CAPTORS.

HE SAYS AMERICA IS HIS REAL

KILLER AND THEN FOLEY IS MURDER.

THE OBAMA ADMINISTRATION SAID

THEY ARE WORKING TO AUTHENTICATE

THE VIDEO, ADDING 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.

AND THE FAMILY OF JIM FOLEY

RELEASED A STATEMENT LATE

TUESDAY NIGHT THAT READS IN PART

WE IMPLORE THE KIDNAPPERS TO

SPARE THE LIVES OF THE REMAINING

HOSTAGES.

LIKE JIM, THEY ARE INNOCENT.

THEY HAVE NO CONTROL OVER

AMERICAN GOVERNMENT POLICY IN

IRAQ, SYRIA OR ANYWHERE IN THE

WORLD.

ANOTHER AMERICAN JOURNALIST IS

SHOWN AT END OF THE VIDEO, THE

EXECUTIONER SPEAKING WITH AN

APPARENT BRITISH ACTION

THREATENS TO TAKE HIS LIFE IF

PRESIDENT OBAMA DOESN'T STOP AIR

STRIKES IN IRAQ.

SOTLOFF KIDNAPPED ON THE

SYRIAN-TURKISH BORDER HAS WORKED

AS A CONTRIBUTOR TO "TIME"

MAGAZINE.

NO ONE KNOWS HOW MANY THOUSANDS

OF SYRIANS AND IRAQIS HAVE DIED

AT HANDS OF ISIS MILITANTS.

ACROSS THEIR STRONGHOLD IN

NORTHERN IRAQ, COLD-BLOODED MASS

KILLINGS OF IRAQI MEN, WOMEN AND

CHILDREN.

>> WE DO HAVE INFORMATION THAT

THEY CONTINUE.

THESE KINDS OF DEPRIVATIONS AND

CRIMES AGAINST HUMANITY, NO

QUESTION ABOUT THAT.

>> Reporter: AFTER DOZENS OF AIR

STRIKES AGAINST ISIS POSITIONS

ACROSS NORTHERN IRAQ, THE GROUP

MAY FEEL PRESSURE, BUT THERE IS

NO SIGN IT'S ABANDONING ITS

VIOLENCE AND HORROR.

ISIS HAS SOME 10,000 FIGHTERS.

IT'S NOW A GROUP THE U.S.
