WASHINGTON- The Pentagon says U.S. forces have conducted an airstrike in Syria targeting the British man known as "Jihadi John" who participated in the beheading videos of two American journalists and the slayings of several other captives.
    
Pentagon press secretary Peter Cook says the airstrike Thursday in Raqqa targeted Mohamed Emwazi. Cook says whether or not Emwazi died in the strike is not clear.
    
A U.S. official says a drone had targeted a vehicle believed to be carrying Emwazi. The official is not authorized to speak publicly and requested anonymity.
    
Emwazi is in the videos showing the killings of journalists Steven Sotloff and James Foley, U.S. aid worker Abdul-Rahman Kassig, British aid workers David Haines and Alan Henning, Japanese journalist Kenji Goto, and a number of other hostages.
