Weapons dealers in Yemen are openly using the social media platform X, formerly known as Twitter, to sell Kalashnikovs, pistols, grenades and grenade-launchers.
The traders operate in the capital Sana’a and other areas under control of the Houthis, a rebel group backed by Iran and proscribed as terrorists by the US and Australian governments.
The advertisements are mostly in Arabic and aimed primarily at Yemeni customers in a country where the number of guns is often said to outnumber the population by three to one.
The BBC has found several examples online, offering weapons at prices in both Yemeni and Saudi riyals.
The words beside the weapons are designed to lure in the buyers.
"Premium craftsmanship and top-notch warranty," says one advertisement. "The Yemeni-modified AK is your best choice."
A demonstration video, filmed at night, shows the seller blasting off a 30-round magazine on full automatic.
Another offers sand-coloured Pakistani-produced Glock pistols for around $900 each.
id call the common use of the term machine gun to be any automatic firearm accurate enough, but you also have a point about inflated language
