**El-Rufai's Toxic Claim: A Matter of National Security** As the nation continues to grapple with issues of national security and governance, a recent development has sent shockwaves across the country. Nasir El-Rufai, a former governor of Kaduna State, has made a startling claim that the Office of the National Security Adviser (ONSA) procured a toxic chemical, thallium sulphate, from a supplier in Poland. This bombshell allegation has left many Nigerians wondering about the implications of such a move. For those who may not be aware, thallium sulphate is a highly toxic substance that can be deadly even in small quantities. Its colourless and odourless nature makes it a potent poison that can be difficult to detect. The claim that ONSA might have sourced this substance raises serious concerns about the safety and security of our citizens. In response to El-Rufai's petition, the ONSA has denied any involvement in the alleged procurement of the toxic chemical. In a letter signed by Brigadier-General O.M. Adesuyi, the NSA's office stated that they have no intention of purchasing such a material and have not initiated any process to do so. However, the matter has been referred to the Department of State Services (DSS) for a comprehensive investigation. This development has significant implications for our nation's security architecture. If El-Rufai's claims are true, it would raise questions about the oversight and accountability mechanisms in place within our national security agencies. On the other hand, if the claims are false, it would be a case of malicious propaganda aimed at undermining the government. As Nigerians, we are entitled to know the truth about these allegations. We hope that the DSS will conduct a thorough investigation and provide us with the facts. Only then can we have a clear understanding of what transpired and take necessary steps to prevent such a scenario in the future. In conclusion, the alleged procurement of thallium sulphate by ONSA is a matter of national security that requires immediate attention. We urge the DSS to conduct a comprehensive investigation and provide us with the facts. Only then can we have peace of mind and confidence in our national security agencies.
