In a statement on Tuesday, Khatibzadeh said the transit of conventional non-military items through Iran to neighboring countries has always been underway.
“The mentioned trucks are crossing Iran simply within the same framework,” he added.
“The Islamic Republic of Iran carefully monitors and controls the trend of transportation and transit of commodities to other countries (via its soil) and does not allow our country’s soil to be used for the transfer of arms and ammunition whatsoever,” he said, according to the Foreign Ministry’s website.
Baku had earlier voiced concern about reports of large arms shipments from Russia to Armenia during and after the fighting.
Last month, Azeri President Ilham Aliyev complained to his Russian counterpart Vladimir Putin about Moscow’s arms sales to Armenia amid the outbreak of fighting between Azerbaijan and Armenia.
