A judge at Lebanon’s highest court suspended the arrest warrants against two former cabinet ministers in the 2020 Beirut port blast case, officials said Tuesday.

The explosion was one of the world’s largest non-nuclear blasts ever recorded.

Judge Sabbouh Suleiman of the Court of Cassation lifted the warrants against former public works minister, Youssef Fenianos, as well as former finance minister and current member of parliament Ali Hassan Khalil, judicial officials said, speaking on condition of anonymity in line with regulations.

More than three years later, there are still no answers to what triggered the explosion, and no one has been held accountable. Rights groups and local media revealed that most state officials knew of the presence of hundreds of tons of ammonium nitrate, a highly explosive material used in fertilizers that had been improperly stored there for years, in the port.
