On Saturday a group of armed men stormed the headquarters of a government building in rural Oregon to protest the "tyranny" of the federal government, threatening violence if law enforcement tries to remove them and calling on "patriots" to join their fight.

It appears the group want the Bureau of Land Management to turn over a wildlife reserve to local ranchers.

Leader Ryan Bundy (son of Cliven Bundy, who carried out a similar standoff over land use in Nevada in 2014) said that the group were willing to use violence.

The group claims to number more than 100 in the occupied buildings, but reporters on the ground say the number appears to be closer to a dozen. They have been holed up since Saturday night local time.

Many commenters online have been quick to point out that the stand-off bears all the hallmarks of a terrorist incident.

For context, here is how the FBI defines terrorism:

The unlawful use of force or violence against persons or property to intimidate or coerce a government, the civilian population, or any segment thereof, in furtherance of political or social objectives.

And the US government has traditionally used four criteria in determining what counts as an act of terror:

Premeditation

Political motivation

Aimed at civilians

Carried out by sub-national groups, rather than the state or army

And yet it is not receiving the coverage expected of such a story, which the Associated Press has reported as "peaceful":

Since the November Paris attacks, which stoked fears across the West about taking in Syrian refugees, right-wing white men in the US have killed people at a Planned Parenthood clinic, shot at Black Lives Matter protesters and held armed rallies outside mosques.
