The threat of the terrorist organization ISIS has been at the forefront of national security and diplomatic discussions. The Free Beacon reports that the organization has posted messages on their social media channels threatening its launch of new terror attacks.

“The messages, carried across the internet via the Telegram networking website, feature the three cities” which are San Francisco, New York, and London, “and call for adherents of the terror group’s radical ideology to ‘kill them all.”

A group that monitors jihadi networks, the Middle East Media Research Institute, or MEMRI, has obtained copies of the group’s threats. MEMRI found that “ISIS…shared five posters on Telegram which threaten and encourage terror attacks in the west…the posters are captioned in poor English and feature background images of San Francisco, New York City, and London.”

On each of the five posters were messages such as “Go and answer the call…Don’t spare none [sic]. Kill them all. It is now time to rise. Slit their throats. Watch them die.” Another poster featured a man in a suicide bomb vest standing in New York City, and another showing Big Ben and London burning.
