‘Bubonic plague weapon’

Plans to create a weaponized form of bubonic plague from infected animals are found on a laptop discovered in former ISIS hideout:

The advantage of biological weapons is that they do not cost a lot of money, while the human casualties can be huge

A fatwa on the justification for the weapon:

If Muslims cannot defeat the kafir [unbelievers] in a different way, it is permissible to use weapons of mass destruction

The laptop is believed to belong to a Tunisian national identified as Muhammad S., who joined ISIS after studying chemistry and physics at two universities in Tunisia’s northeast. A suggestion for weaponisation:

Use small grenades with the virus, and throw them in closed areas like metros, soccer stadiums, or entertainment centers. Best to do it next to the air-conditioning. It also can be used during suicide operations.

Experts say that the document is no indication that ISIS are already in possession of such weapons, but say that the longer the group remains active, the more likely it is to develop weapons capable of mass destruction.
