Lebanese officials say that thousands of tons of ammonium nitrate stored in a warehouse at the port in Beirut caused the massive explosion on August 4. The blast devastated the city, killing more than 130 people, injuring at least 4,000 and displacing 3,00,000 from their homes. Ammonium nitrate is used in fertilizer and in the mining industry as an explosive to blast rock and move mounds of earth. Reportedly, it was used by white supremacists to blow up the Alfred P. Murrah Federal Building in Oklahoma City, Oklahoma in 1995. Watch the video to know more.
