An “automatic assumption” to link terrorist acts with mental illness unfairly stigmatizes the millions of people with mental health problems and impedes prevention efforts, psychiatry experts warn. They explain that terrorist groups and networks seem to avoid recruiting people with mental health problems, “probably because they share some of the same stigmatized views as the rest of society and see people with mental health conditions as unreliable, difficult to train, and a security threat.”

The U.S. on Monday destroyed an ISIS chemical manufacturing facility in Iraq, which posed a “significant chemical [weapons] threat.” Footage of Monday air strikes showed twelve aircraft hitting a sprawling industrial site in Mosul. The hits were followed by huge explosions in multiple buildings and storage facilities. The buildings were quickly engulfed by flames, and heavy plumes of dark smoke rose into the air. USAF spokesman said that fifty individual targets were hit in the attack.

Major disasters pose difficult challenges for responders on the ground and for higher-level officials trying to direct operations. Some events are novel because of their scale, while others involve challenges that no one may ever have envisioned. Communities need to bring their response agencies together regularly to plan and practice. This can develop and maintain knowledge and relationships that will enable them to work together effectively under the high stress of a future attack or disaster. Any community can do this, but many have not. Where training and practice have taken place, these tools have worked. They can be improved, but the most important priority is getting more communities to practice using them more regularly, before the next disaster. One important way this nation can honor the victims of 9/11 is by using these lessons to create the conditions for even better coordination in future events.

France’s prime minister Manuel Valls warned on Sunday that some 15,000 French citizens could be in the process of being radicalized. His warning came a day after the police arrested a 15-year-old boy at his Paris home in order to thwart a planned weekend terrorist attack.

In a video recording released late Sunday, Colombia’s Marxist FARC rebels have apologized for the “great pain” they caused by kidnapping thousands of people and holding them for ransom to fund their 52-year war against successive Colombian governments. Official figures show that some 27,000 people were kidnapped between 1970 and 2010. In addition to kidnapping, the FARC used extortion and the drug trade to finance its campaign. On 24 August the leadership of the FARC igned a formal agreement with the Colombian government to put an end to South America’s longest war.

Hamas spends an annual $100 million on its military infrastructure in order to prepare for its next war against Israel. Roughly $40 million is spent on employing around 1,500 diggers to build the Iran-backed terror organization’s network of tunnels. Despite the financial hardships experienced by Gaza residents, Hamas, which in 2014 had a budget of around $530 million, is intent on increasing its military spending. In addition to digging tunnels, it hopes to upgrade its capabilities, which were degraded during its war with Israel two years ago, and is seeking to develop more precise rockets that could evade Israel’s Iron Dome defensive shield.

The French security services are looking for a young woman after a car carrying seven gas cylinders was discovered Saturday parking near Notre-Dame cathedral in Paris. The car was found on a Seine riverside stretch called the Quai de Montebello, only meters from the cathedral. The father of the missing 19-year old – himself on the French intelligence services’ terror watch list – informed the police that his daughter, who was being monitored by the police for expressing her desire to go to Syria to join ISIS, had disappeared with his car.

If you can imagine a disaster involving explosives or the release of nuclear, biological, chemical, or radioactive material, there is a pretty good chance a group of subject-matter experts within the FBI has built an elaborate scenario around it and tested how well emergency responders face up to it. It is the main jobs of the Weapons of Mass Destruction (WMD) Directorate — to imagine worst-case scenarios and then devise ways to prevent and prepare for them. The Directorate was created ten years ago, on 26 July 2006.

Since the beginning of the conflicts in Iraq and Afghanistan, the United States has dramatically increased use of unmanned drones, developing technology to target and kill those identified as being terrorist leaders. Current U.S. policies on using drones for targeted killing are characterized by ambiguities in interpretations of international law and too many generalities, despite recent efforts by the Obama administration to clarify the policies, a new report finds.
