The latest issue of the Islamic State's weekly newspaper al-Naba released two days ago warned that another terrorist attack in Britain was "definitely coming."
Al-Naba, a 16-page color newsletter, is distributed within ISIS territory but is also posted and distributed online via the usual ISIS mediums such as Telegram and social media.
Britain, said an article within the newsletter titled "Blessed Battle of Manchester: A new lesson for tyrants, Crusader States," thought it "was safe from the wounds of the Mujahideen."
"Protected by the sea they have long relied on isolating themselves" and thought "their exit from the European Union would save them."
"A soldier from the Islamic State" in Manchester, the article continued, "has unleashed terror throughout their country, they rushed to spread the army in the cities, mobilizing police and security in the streets for fear of a new attack," which "is inevitable, God willing."
ISIS branded British security and vigilance across cities and towns a "costly, exhausting situation."
ISIS also needled the UK for "their abandonment of John Cantlie," a British war correspondent who was kidnapped in Syria in 2012 and has been forced to write propaganda pieces and film video segments for his ISIS captors. Cantlie was last seen in December ISIS videos reporting from Mosul.
Though Al-Naba usually focuses on events within ISIS territory, Ohio State terrorist Abdul Razak Ali Artan was featured in a December article calling the first-year student "one of the Mujahideen of the Islamic State" who "attacked a gathering" at the school, causing "serious injuries."
British authorities are treating tonight's ramming of pedestrians on London Bridge by a white van speeding at about 50 mph and a stabbing at nearby Borough Market as terrorist incidents.
Last month in Rumiyah magazine, which is published in several languages including English, ISIS published a remedial step-by-step pictorial for lone jihadists on how to use a heavy vehicle to kill, walking would-be terrorists through how to acquire a vehicle and which targets to strike.
"The ideal vehicle," said ISIS, has a "slightly raised chassis and bumper," is a "double-wheeled, load-bearing truck" that "large in size, heavy in weight" and is "fast in speed or rate of acceleration."
The suggestions for ideal targets also illustrated examples. Corresponding to "large outdoor festivals, conventions, celebrations, and parades" was a photo of an LGBT event. As during the Pulse nightclub attack last summer, Ramadan is currently overlapping with LGBT Pride Month.
A busy London street next to an Underground stop was shown as the "pedestrian-congested streets" example. After "outdoor markets," ISIS suggested "outdoor rallies," and used a photo of a 2012 May Day rally in Paris.
