Earlier this morning, a knife wielding man attacked French security personnel guarding the entrance to the Louvre. He was reportedly subdued only after non-lethal means failed to stop the threat, and shots were fired.
The attacker, whose identity and motivation remains unclear, was seriously injured.
French soldiers have been deployed to major tourist destinations and government buildings throughout France following the string of Islamic extremist attacks in their country over the last two years, which have claimed the lives of 237 French citizens and others.
Knife attacks do not have the capability to produce mass casualties in the style of the Bataclan Massacre, or the Charlie Hebdo murders, but they are cheap, easy to plan, and surprisingly effective in achieving terrorist goals.
