ISIS members are preparing “an event to warn the U.S” to not involve themselves in Iraq.

A person identifying himself as “Alanbari Daysam” has posted a series of threats to the United States homeland via Twitter today.

Calling for ISIS members to attack the United States, Dayaam posts pictures of suicide vests and instructs followers to “enter U.S. cities and marketplaces with these vests and detonate them, killing American citizens”

In other Tweets, “Daysam” advocates advice from Osama Bin Laden telling Muslims not to ask before committing Jihad against America and to poison American drinking water.
