An Islamic State jihadist thought to be a leader of ISIS in Great Britain, has tweeted out Pamela Geller's home address and urged that the activist be murdered.

The threat comes on the heels of the revelation last week that a plot to kill Geller by three Boston jihadists resulted in the death of one of the would be terrorists when they changed their plan and decided to go after police.

International Business Times:

The personal address of an anti-Muslim activist was tweeted Friday from a Twitter account bearing the name of a man believed to be a British Islamic State jihadist kingpin. The tweet about Pamela Geller, who heads a group called the American Freedom Defense Initiative, came just hours after a third man connected to a plot to kill her and murder Boston police was arrested.

"#GoForth," the Tweet urged via a hashtag after revealing Geller's New York City address, apartment number and all. The Twitter account that sent out the address has since been suspended.

In May, two gunmen were killed and one security guard was injured in Texas during a controversial “draw Muhammad” contest that was organized by Geller. ISIS soon after claimed responsibility for the attack at the contest, which welcomed renditions of the Prophet Muhammad, a provocative act for many Muslims who believe that the prophet should not be depicted or mocked in any way.

The contest in Texas was organized months after the January Charlie Hebdo shooting in Paris, where nearly a dozen staffers were killed for the satirical publication's provocative depictions of Muhammad on a series of the tabloid’s covers. 

The two men charged in Boston with the plot to kill Geller reportedly were working with a third man who was killed by police last week.

Geller has been taking sensible precautions but this really ups the ante. She has courage, but this is no time to be brave. There are too many fanatics inspired by the terrorists who now have a target building. There have been two murder plots against the activist so far, and you have to think that there are several others yet to be discovered. Geller's problem is that same as it is with any terrorist plot; we have to successfully head off assassination attempts 100% of the time while the terrorists only have to be successful once.
