A massive new study indicates there is a statistical link between hotter temperatures generated by climate change and the risk of armed conflicts in sub-Saharan Africa. A research team assessed more than 78,000 armed conflicts between 1980 and 2012 in the Sahel region of Africa — a semi-arid belt just south of the Saharan Desert that spans about 3,000 miles and more than a dozen countries from the Atlantic to the Indian oceans. The team was looking for links between armed conflicts and temperature and rainfall anomalies, as well as assessing other causes of violence in the Sahel.

Francisco Martinez, Spain’s state secretary for security, claimed that ISIS fighters are planning to carry out “lone wolf” attacks using biological weapons. He cites conversations uncovered from secret chat rooms used by would-be militants. Bioterrorism experts say the use of Ebola for bioterrorism is highly unlikely. “Assuming a terrorist organization manages to capture a suitable Ebola host, extract the virus, weaponize the virus, transport the virus to a populated city and deliver the virus, it is entirely likely that the sub-optimal climatic conditions of a Western city will kill it off relatively quickly,” says one expert.

Abu Bakr al-Baghdadi, the leader of the Islamic State of Iraq and Syria (ISIS), was “critically wounded” early Saturday when a U.S. air strike hit two ISIS targets in the town of al-Qaim in western Iraq. The attacks early Saturday morning included an air attack on a 10-car convoy on the outskirts of the border town of al-Qaim, and a combined air attack and ground assault on a house in al-Qaim where ISIS leaders were meeting at the time. Three senior ISIS figures were confirmed killed: Abdur Rahman al-Athaee, also known as Abu Sajar, a senior aide to ISIS leader who was particularly close to al-Baghdadi; Adnan Latif al-Suweidi, the overall leader of Anbar province; and Bashar al-Muhandi, ISIS’s leader in the Euphrates valley.

U.S. airstrikes in Syria overnight successfully hit a group of al-Qaeda-affiliated militants, killing the group’s top bomb-maker. David Drugeon, a French Islamist militant, was killed along with other Khorasan Group members near Saramada, a town eighteen miles northeast of Idlib in Syria’s northwest. Drugeon escaped an earlier U.S. airstrike, on 22 September, which was aimed to take him out. The innovative Drudgeon was designing bombs made out of clothing dipped in explosive solution and explosives concealed in personal electronics. In July, the Transportation Security Administration (TSA) banned cell phones without electronic charge from airplane cabins in response to the intelligence coming in about Drudgeon’s designs, much of it fragmentary.

The new director of Government Communications Headquarters (GCHQ), the U.K. intelligence organization responsible for providing signals intelligence (SIGINT) and information assurance to the British government and armed forces, said that privacy has never been “an absolute right.” Robert Hannigan used his first public intervention since becoming head of Britain’s surveillance agency to charge U.S. technology companies of becoming “the command and control networks of choice” for terrorists.

At least 3,000 of the 15,000 foreign fighters in Syria are from Australia and Europe. DHS has introduced new screening measures for travelers from Europe, Australia, and other allied nations due to concerns about the increasing number of Islamist militants who have fought in Syria and Iraq alongside the Islamic State (ISIS) and could travel freely to the United States using their Western passports.

University of Central Florida(UCF) professor Dr. Jonathan Matusitz is facing backlash from some groups which claim that his class on terrorism and communication is based on a biased view and a hatred of Islam. Students at the University of California-Berkeleybegan to protest the university’s selection of television personality Bill Maher as the mid-year commencement speaker on 20 December, describing his comments on Islam as racist, divisive, and offensive to many students. UCF says it stands behind Matusitz, and UC-Berkeley says Maher’s invitation stands.

William Hague, former British foreign secretary, said that British jihadists returning to the United Kingdom from Syria and Iraq will be helped by the government as long as they have “good intentions.” Hague said that the U.K. authorities are prepared to assist people who come back to Britain after fighting in the Middle East as long as it can be established that they are not planning attacks in the United Kingdom.

With fears growing over chemical and biological weapons falling into the wrong hands, scientists are developing microrockets to fight back against these dangerous agents. Scientists point out that titanium dioxide is one of the most promising materials available for degrading chemical and biological warfare agents. It does not require harsh chemicals or result in toxic by-products. There is no way, however, actively to mix titanium dioxide in waterways, so scientists have been working on ways to propel titanium dioxide around to accelerate the decontamination process without the need for active stirring.
