The San Bernardino shootings. The killing rampage this week in a Baghdad mall. On Thursday, it was the explosion that ripped through a Starbucks in Jakarta.
In each of those terrorist attacks, an outlet called the Amaq News Agency was first with the news that the Islamic State was going to claim responsibility.
The agency has been getting the scoops because it gets tips straight from ISIS, and for those of us on the terrorism beat, that has made Amaq a must-read every time a bomb goes off.
It publishes a heavy stream of short releases on an encrypted phone app called Telegram, functioning much like an official news agency might inside a totalitarian state.
The alerts, articles and videos take on the trappings of mainstream journalism, with "Breaking News" and "Exclusive" headings.
And its reporters try to appear objective, toning down the jihadist hyperbole ISIS uses in its official releases.
(The Jakarta attackers were "Islamic State fighters" rather than the ISIS-preferred "soldiers of the Caliphate." Victims are "foreign citizens" rather than "Crusaders.")
Make no mistake, though: Amaq is putting out the Islamic State's message, and the veneer of separation between the terrorist group and what has now become its unacknowledged wire service is quickly disintegrating.
Though the group is not officially part of the ISIS media apparatus, it functions much that way.
"It has become much more assimilated into the Islamic State's propaganda infrastructure, and now it's a fully fledged and very important part of it.
It has become the first point of publication for claims of responsibility by the group — though not as a rule," said Charlie Winter, a senior researcher at the Transcultural Conflict and Violence Initiative at Georgia State.
He pointed out that one of the biggest attacks — the Nov. 13 killings in Paris — followed the more traditional route, with the claim of responsibility published directly by ISIS.
The Islamic State maintains its official Al Bayan radio station, which puts out daily news bulletins, and its monthly magazine Dabiq, as well as many production companies that put out its grisly videos.
