The widow of Lebanese intellectual Lokman Slim, Monika Borgmann, urged the U.N. Human Rights Council "to commit itself" to a "fact-finding mission to support Lebanon and its people in its calls for justice and accountability."

Lebanon's own investigation into the blast "is not advancing and is hampered," Borgmann said at a ceremony marking the second anniversary of Slim's killing at his home in the Beirut southern suburb of Haret Hreik.

In one of Slim's last TV appearances, he accused the Syrian regime of having links to an ammonium nitrate shipment that caused the blast.

Borgmann urged any U.N. fact-finding mission to investigate Slim's killing and two other deaths that she said "could be linked to the port explosion."

She was referring to Mounir Abu Rjeili, a retired colonel from the customs administration, and amateur military photographer Joe Bejjany, the circumstances of whose December 2020 deaths have also not been clarified.
