A British ISIS supporter has published the name and address of the Navy Seal who killed Osama bin Laden and called on American extremists to execute him.

Mirror Online has been monitoring jihadi chat on social media and has spotted several people linking to a text file containing instructions on how to find Robert O'Neill, who claimed to have killed the al Qaeda chief.

This information was shared by an unnamed British extremist, who dubbed O'Neill a "number one target" and called for his immediate death.

The address is now being shared on social media along with a sinister hashtag.

Dozens of extremists have now republished the Navy Seal's private information, despite apparent censorship attempts by social media firms and the website which is hosting the information.

"I leave this info of Robert O'Neill for my brothers in America and Al Qaeda in the U.S, as a number one target to eventually hunt down and kill," the ISIS supporter wrote.

The anonymous jihadi slammed O'Neil for "traveling around America putting on seminars boasting about killing Sheikh Osama".

He also posted a link to an story in the International Business Times in whichO'Neill's father said the family were "not afraid of ISIS".

The Navy Seal went public with his claims in a documentary called "The Man Who Killed Osama Bin Laden".

He is understood to have separated from his wife over security concerns.

"We're actually looking into changing my name," she told Esquire in 2013.

"Changing the kids' names, taking my husband's name off the house, paying off our cars.

"Essentially deleting him from our lives, but for safety reasons."

We have contacted Robert O'Neill to warn him about the threats, but he has not yet responded.
