Former Kaduna State Governor Nasir el-Rufai has formally requested clarification from National Security Adviser Nuhu Ribadu over allegations that the Office of the National Security Adviser (ONSA) imported approximately 10 kilograms of thallium sulphate, a highly toxic chemical, from a Polish supplier .
In a letter dated January 30, 2026, and shared on X, el-Rufai described thallium salts as “odourless and colourless” substances subject to strict international controls, raising concerns about public safety and transparency .
He demanded details on the intended purpose, supplier identity, quantity, storage arrangements, and regulatory oversight by NAFDAC and NCDC . ONSA has since denied the allegation, referring it to the Department of State Services (DSS) for investigation .
Key Points:
The allegation raises serious public safety concerns over potential misuse of a lethal, undetectable toxin.
It deepens the political feud between el-Rufai and Ribadu following the former’s recent airport arrest attempt.
Citizens demand transparency, while ONSA faces pressure to prove no procurement occurred.
This signals the weaponisation of national security agencies and procurement in political warfare.
The timing, with DSS investigation, shifts the burden of proof onto el-Rufai to substantiate claims.
The DSS will now investigate el-Rufai’s allegations, with the former governor expected to provide evidence supporting his claims of toxic chemical importation.
