A Twitter account reportedly used by the Al Nusra Al Maqdisia (The Supporters of Jerusalem), a group that has pledged its loyalty to the Islamic State of Iraq and the Levant (ISIS), recently issued death threats against Twitter employees in the United States. The @dawlamoon account was quickly suspended, but not after urging "lone wolf attacks" targeting Twitter employees at the company's San Francisco headquarters.
ISIS and its affiliate groups use social media to recruit new members, spread propaganda, and antagonize rivals - but official terrorist group accounts are being purged from Twitter and other networks - which has apparently upset the Al Nusra Al Maqdisia.
It's unknown if Twitter is boosting security at its headquarters, but the federal government is aware of the tweets.
Some of the tweets included messages such as:
"The time has arrived to respond to Twitter's management by directly attacking their employees and physically assassinating them! Those who will carry this out are the sleeper cells of death."
"Every Twitter employee in San Francisco in the United States should bear in mind and watch over himself because on his doorstep there might be a lone wolf assassin waiting."
