Azerbaijan’s embassy in Iran was attacked on Friday morning by unknown gunmen and the incident left one dead and two injured, the Azerbaijani Foreign Ministry said in a statement.
“On January 27 … an armed attack took place against the Embassy of Azerbaijan in Iran. A man armed with a Kalashnikov killed the chief guard of the diplomatic mission,” the statement said.
Two other embassy guards were injured and are in “satisfactory condition”, according to the same source.
An investigation is underway, the statement added, without further details.
Iran, home to millions of Azeris, has long accused its neighbor of fomenting separatist sentiment on its territory.
Relations between Baku and Tehran have traditionally been delicate, with Turkish-speaking Azerbaijan being a close ally of Turkey, a historical rival of Iran.
Tehran also fears that Azerbaijani territory could be used for a possible offensive against Iran by Israel, the main arms supplier to Baku.
