I hadn’t seen this until recently.

This 1991 IAEA report has a few paragraphs about accidents involving the transportation of UF6.:

This December 21 DAE report provides some details about India’s nuclear energy program:

This report contains a history of the IAEA and the ME WMDZ:

The 2020 NASIC report has a paragraph about solid- vs. liquid-fueled missiles:

The trend in modern missile systems has been toward the use of solid propellants because of their reduced logistical requirements and simplicity of operation. However, some nations have greater access to liquid-propellant technology and continue to develop new liquid-propellant missiles. In addition, liquid-propellant missiles can be more efficient than solid-propellant missiles for very heavy payloads. The missiles with the world’s heaviest payloads, the Russian SS- 18 and Chinese CSS-4, are liquid-propellant ICBMs, and Russia is developing a new heavy-lift, liquid-propellant ICBM called the Sarmat.

This past June, the UN published the final report of the Group of Governmental Experts to Further Consider Nuclear Disarmament Verification Issues

the Group developed the following working definition to guide its work: nuclear disarmament verification is a process driven by states parties to a specific treaty, agreement or arrangement, of gathering and analysing information, based on agreed technologies, methodologies and procedures, to enable assessment of compliance with relevant nuclear disarmament commitments and obligations, or an assessment of adherence to unilateral undertakings as set out in a verification arrangement, with the overarching goal of achieving and maintaining a world free of nuclear weapons.

From the God Dethroned album Passiondale:

Vicious death creeping across the fields
Mustard gas, a deadly hellish fiend
A choking grip is locked around your neck
Vomit blood, your face turns grey, you’re dead

From an excerpt of  R Chidambaram’s memoirs:

Money was allocated from a ‘secret fund’ maintained by the Defence Research and Development Organisation (DRDO). In the 1990s, Prime Minister PV Narasimha Rao told scientists ‘to be prepared to carry out the tests anytime on 10 days’ notice’. But the tests were put off for fear of the economic fallout. Atal Behari Vajpayee gave the go-ahead soon after he became the PM in 1996. Scientists were in Pokhran and had placed the main nuclear device in the chamber and sealed it. They were ready to place the same in the shaft when the test was called off due to the no-confidence motion against the Vajpayee government. The tests were finally conducted in 1998. “The extra time of two years allowed us to develop more sophisticated devices,” Chidambaram says in the book.

From this July UNSC report:

One Member State reported an increasing focus by the Da’esh affiliate in Libya to recruit scientists capable of producing biological materials or handling sophisticated technological devices to use in terrorist attacks.

From this July UNSC report:

The situation in Europe remained stable, with a slight increase in the number of thwarted terrorist acts, mostly against soft targets and places of worship. Most attacks were conducted by individuals without a direct affiliation with Da’esh, and some appeared to have been triggered by acts perceived as hostile towards Islam. According to one Member State, some of the attackers had aspired to use explosives and chemical toxins.
