"Lebanon's President, Michel Aoun, blamed the detonation on 2,750 tonnes of ammonium nitrate that he said had been stored unsafely at a warehouse in the port.
A similar amount of the chemical arrived on a Moldovan-flagged cargo ship, the MV Rhosus, which docked in Beirut in 2013 after suffering technical problems while sailing from Georgia to Mozambique.
