Syria's state news agency, Sana, reported that an explosion in Aleppo on July 26 killed around 15 soldiers and wounded 50 others. The Syrian officials had claimed that highly explosive products blew up due to an accidental fire at the facility, and no sabotage was involved. They had reasoned that the increase in ambient temperatures up to 50 degrees Celsius caused an ammunition dump to explode, killing and wounding the soldiers.
The Chemical Weapons Convention which marked its tenth anniversary on April 29 bans the development, production, acquisition and use of chemical agents (e.g. Vesicants and nerve agents) and requires the destruction of existing stockpiles.
