Iran says it will take "diplomatic countermeasures" in response to Azerbaijan radical and unconstructive positions against Iranian teachers and diplomats residing in Baku.
In a statement on Friday, Iranian Foreign Ministry spokesman Nasser Kan'ani said Tehran believes that such moves by the Azerbaijani government are in contradiction to the neighborly principles.
"The Islamic Republic of Iran emphasizes the [importance of] observing the principles and basics of the neighborhood policy and paying heed to the sinister goals of the Zionist regime (Israel) in creating differences and tension in the relations among Muslim countries while at the same time, it has diplomatic countermeasure on its agenda," Kan'ani added.
Azerbaijan said on Thursday it has declared four Iranian embassy employees persona non grata, claiming the diplomats conducted "provocative actions" in the latest deterioration of relations between the two neighbors.
The move came hours after Baku said it arrested six men, who it claimed were linked to Iranian secret services and were plotting a coup in the Caspian nation.
Azerbaijans relations with Iran were strained in January following anattackon the Eurasian countrys embassy in Tehran.
Azerbaijan closed its diplomatic mission following the incidentand evacuated staff over what it called a terrorist act, with President Ilham Aliyev blaming it on the Iranian establishment.
This is while an initial investigation pointed to personal and family-related problemsas the motive of the assailant.
Recent estimates show that Azerbaijan has become Israels largest supplier of oil while Tel Aviv is now responsible for almost 70 percent of Bakus weapons.
Elsewhere in his remarks, Kan'ani urged Azerbaijan to act based on mutual respect and good neighborliness and avoid pursuing the demands of the Zionists and enemies in the region.
The Iranian spokesperson said the crisis and chaos have engulfed the entire occupied Palestinian territories and Israel is in its most unstable internal situation but at the same time, the regime attacked the fasting Muslims and desecrated the al-Aqsa Mosque to play a blame game in the face of multi-layered crises in the occupied territories.
