Just months after five students at Montreal’s Collège de Maisonneuveleft Canada to join the Islamic State in Syria, a young couple, El Mahdi Jamali and Sabrine Djaermane, who attended the same school, were arrested last Tuesday for what police allege were plans to commit terrorist acts. Since the arrest, school officials have met with terrorism and extremism experts to help analyze if the school itself had been a breeding ground for extremists. Some locals familiar with the school have pointed fingers at Adil Charkaoui, an Islamic leader in Montreal who rents the school’s facilities for a weekend Muslim youth group, and was once probed by federal agents as a suspected al-Qaeda sleeper agent.

David Albright is the founder and president of the Washington, D.C.-based non-profit Institute for Science and International Security (ISIS), and author of several books on fissile materials and nuclear weapons proliferation. In a testimony before the House Foreign Affairs Committee on Wednesday, and an interview with Deutsche Welle on Thursday, Albrights says that there is every reason to be suspicious of Iran because it has cheated on its obligations in the past and has been uncooperative on an ongoing basis. Iran has also built many sites in secret, so any agreement with Iran should have extra insurance — a more powerful inspection and verification tool to try to ferret out any secret nuclear activities or facilities that Iran would build. Still, a negotiated deal, if it includes sufficiently robust inspection and verification measures, would be a more effective way than a military strike to make sure Iran does not develop nuclear weapons.

Detonating a nuclear device or dirty bomb in the United States has long been goal of terrorists groups including al-Qaeda. Doing so, however, would require access to nuclear materials and a way to smuggle them into the country. Experts note the nexus between drug organizations, crime groups, and violent extremists and the trafficking of radiological and nuclear materials. A new report points out that al-Qaeda, Hezbollah, and Colombia’s FARC are the three organizations with the motivation and capability to obtain a radiological or nuclear device.

In December 1982, Rodney Wilkinson planted four bombs that caused $519 million in damages at the Koeberg nuclear power plant north of Cape Town, South Africa. The attack, which many believe to be the most ambitious and successful terror attack against a nuclear facility, remains a symbol of African National Congress (ANC) war against South Africa’s then-apartheid government. The 1982 Koeberg assault, however, and a 2007 raidby two yet-to-be-identified armed groups on South Africa’s Pelindaba nuclear research site, are at the root of U.S. concerns about the safety of South Africa’s roughly 485 pounds stockpile of highly enriched uranium.

Evidence strongly suggests that Syrian government helicopters dropped barrel bombs filled with cylinders of chlorine gas on three towns in Northern Syria in mid-April 2014, Human Rights Watch said earlier this week. These attacks used an industrial chemical as a weapon, an act banned by the international treaty prohibiting chemical weapons that Syria joined in October 2013. The Syrian government is the only party to the conflict with helicopters and other aircraft.

Muhammad Kamaruzzaman, 62, an assistant secretary general of the Bangladeshi Islamist Jamaat-e-Islami party, was hanged Saturday for crimes committed during the 1971 bloody war between Bengali nationalists and the Pakistani army. A special war crimes tribunal found him guilty of heading a Muslim militia group which was responsible for a massacre of at least 120 unarmed farmers during the conflict. The hanging Kamaruzzman is likely to galvanize the Islamists to intensify their campaign of civil and economic disruption and destabilization. The Islamists have also joined non-Islamist opposition parties, chief among them the major opposition party, the BNP, in an effort to topple the government.

For more than a year, there have been numerous reports of chemical weapons attacks in Syria. This includes reported incidents which occurred in late March, as thousands of Syrians fled the city of Idlib in the face of a government-rebel stand-off. According to witnesses, chemical weapons were used. UN resolutions condemning the use of chemical weapons, however, do not imply immediate action to stop such use. The use of chlorine as a weapon in Syria thus goes on — and there is so far little evidence that the world’s major powers have the wherewithal to bring those responsible to justice. Continued geopolitical wrangling over Syria leaves those documenting the continuation of war crimes there almost completely powerless to stop what is happening. For now, the best we can hope for is that relevant organizations are allowed to continue to gather evidence for future trials —– and that pressure is put on all states to prosecute suspected perpetrators. This is to ensure that those who are committing such atrocities know that they will eventually be held to account.

Canada’s national anti-terrorism program, which aims to identify signs of radicalization in young people and then connect them with social services, has been long-delayed, leading some communities to institute programs of their own with outside assistance.

As Kenya is trying to cope with the grief following last Thursday’s al-Shabaab massacre of 148 Christian students at Garissa University in north-east Kenya, analysts and scholars are focused on the implications of the attack for the future of Kenya. These analysts say that the intensifying terror campaign by the Islamist al-Shabaab may gradually, but inexorably, deepens the religious divisions in Kenya, a country which was once seen as an island of stability and progress in a volatile region. Since independence in 1963, successive Kenyan governments have purposefully neglected the Muslim north-east, a region mired in debilitating poverty and lack of opportunity. As is the case with Boko Haram in north-east Nigeria, al-Shabaab, too, is exploiting regional grievances and the sense of alienation to establish itself as the champion of the marginalized Muslim communities in the north-east. Since 2011, the central government has begun to allocate more funds to development projects in the north-east, but the steady departure of thousands of Christians, many of them professionals – teachers, medical personnel, engineers, agronomists – from the dangerous north-east for safer places in central and south Kenya, has undermined these efforts.
