Five people were killed and four injured in a blast inside a Syrian army ammunition depot alongside the Homs-Hama road in the centre of the country, Iran's state-run TV channel Al-Alam said today.
According to Reuters, the Iranian channel reported the explosion happened during a routine maintenance operation inside the depot.
Iran, a main backer of Syrian President Bashar Al-Assad, has a military presence, directly and through proxy militias, across Syria including the region of Homs. The report did not indicate the nationality of the casualties.
Syria has been ravaged by a civil war since early 2011 when the Assad regime cracked down on pro-democracy protesters.
Hundreds of thousands of people have been killed and more than ten million displaced, according to UN estimates.
