Iran Foreign Ministry has summoned the Yemeni charg d'affaires to protest the fatal shooting of an Iranian diplomat in the Yemeni capital, Sanaa.
The Foreign Ministry reminded the Yemeni Embassy official that under international rules and regulations, governments are responsible for the security of foreign diplomats.
Tehran also called on Sanaa to immediately investigate the attack and bring to justice those behind it.
On Saturday, the commercial attach of the Iranian Embassy in Yemen was shot by members of a terrorist group outside the Iranian ambassadors residence in Sanaa.
"Unidentified assailants in a van fired on the diplomat three times as he was leaving the ambassador's residence near a shopping center in Hadda," a Yemeni police source told AFP.
The assailants first tried to kidnap the Iranian diplomat but when they faced resistance, opened fire on him.
The diplomat who was seriously injured succumbed to his wounds at hospital.
Iranian Foreign Ministry Spokeswoman Marzieh Afkham strongly condemned the terrorist attack, saying that Yemeni authorities are investigating the incident.
