Ninety-eight containers of explosives self-detonate killing 13 people in Zygi, Cyprus.

On 11 July 2011, at Evangelos Florakis Naval Base, situated at Mari, Larnaca District in Cyprus, a large amount of ammunition and military explosives self-detonated, killing 13 people, including the Commander of the Cyprus Navy, Andreas Ioannides, the base commander, Lambros Lambrou, and six firefighters. A further 62 people were injured. The explosion was the worst peacetime military accident ever recorded in Cyprus, with a yield of approximately 481 tons TNT equivalent, as determined by the official investigation into the accident.
