Just after 6pm on August 4, 2020. Zero Hour. The fire in Beirut Port's Warehouse 12 had grown in intensity. It was out of control. A fire crew arrived to try to tackle the blaze, but it was like nothing they had ever seen before. They called for backup. Ghassan Hasrouty and his colleagues were still working in the silos next door, offloading grain from the ship that docked earlier in the day. They’re just metres from Warehouse 12 and the deadly stockpile of ammonium nitrate. Bystanders living in the neighbourhood around the port came to their windows and on to their balconies to watch the clouds of smoke rise into the pale blue sky. Many, however, are unaware anything is wrong. Those like Sarah Copland, an Australian UN employee who’s feeding her son Isaac, 2, next to the big glass windows of the family’s dining room in a quiet Beirut neighbourhood less than a kilometre away from the fire. This is Episode 3 of The Blast. It’s the story of what happened when Beirut blew up, told by the people who were there. This episode contains witness accounts of the events of August 4, 2020, that some listeners may find distressing.

Finbar, like many others in Beirut that day, was badly injured in the explosion. Now, a year on, he is looking to get answers to questions that so many in Lebanon have — who was responsible for the Beirut blast, how did the ammonium nitrate end up there, who knew about it and what caused the explosion. <i>The Blast</i> from <a href="https://audioboom.com/channel/beyond-the-headlines">Beyond the Headlines</a> traces the events of that tragic day. <a href="https://www.thenationalnews.com/podcasts/beyond-the-headlines/2021/08/02/the-blast-episode-1-how-the-ammonium-nitrate-that-blew-up-beirut-got-to-lebanon/" target="_blank">In Episode 1</a>, Finbar enlists Erin Clare Brown, <i>The National</i>’s Tunis correspondent and resident Russian speaker. They track down Boris Prokoshev, the captain of the <i>Rhosus</i> — the ship that first brought the cargo of ammonium nitrate to Beirut Port.
