"The Russian vessel, named MV Rhosus, carrying agricultural fertilizer with 2,750 metric tons of ammonium nitrate and en route to Mozambique hit a financial snag and docked in the Beruit port in 2013, according to legal documents and Lebanese officials, the Washington Post reported."
We'll wait until investigation is over.
Has anyone done the math on whether or not that amount of fertilizer would create the size of the explosion witnessed?
