WASHINGTON – U.S. forces targeted "Jihadi John" in an airstrike in Raqqa, Syria, the Pentagon announced Thursday night.
It was not immediately clear whether the strike was successful.
"Jihadi John," whom Western officials have identified as Mohammed Emwazi, has appeared in a series of brutal ISIS execution videos, taunting Western leaders in a British accent.
Pentagon Press Secretary Peter Cook announced the strike in a statement.
"Emwazi, a British citizen, participated in the videos showing the murders of U.S. 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.
"We are assessing the results of tonight's operation and will provide additional information as and where appropriate," Cook said.
