A Twitter account with 21,000 followers naming itself the “League of Supporters” called for ISIL sympathisers to post messages online on Friday warning the U.S. not to carry out any strikes.

Among hundreds of supportive responses, one user posted, “As our martyred sheikh Osama bin Laden said, you need not consult anyone about killing Americans.”
