Bangladesh has condemns the recent attacks on the Embassy of the Kingdom of Saudi Arabia in Tehran and its Consulate in Mashhad.
“Such acts are in clear violation of the Vienna Convention on Diplomatic Relations, 1961 and the Vienna Convention on Consular Relations, 1963,” said a press note issued by the Ministry of Foreign Affairs on Wednesday.
Calling upon the Republic of Iran to take urgent necessary measures to stop recurrence of such incidents, the release further stated: “It is the responsibility of the host Government to accord necessary protection to the diplomatic and consular missions within its jurisdiction as these are inviolable under the international law.”
Iranian protesters stormed the Saudi Embassy in Tehran early on Sunday and Shia Muslim Iran's top leader predicted "divine vengeance" for Saudi Arabia's execution of a prominent Shia cleric.
Demonstrators massed at the embassy gates to protest against cleric Nimr al-Nimr's execution broke into the building, smashed furniture and started fires before being ejected by police.
Iran's foreign ministry called for calm and urged protesters to respect the diplomatic premises. Tehran's police chief said that an unspecified number of "unruly elements" had been arrested for attacking the embassy with petrol bombs and rocks.
A prosecutor said 40 people were arrested, state media said.
Iranian Supreme Leader Ayatollah Ali Khamenei, criticizing Saudi Arabia for the second straight day over Nimr's execution, said politicians in the Sunni kingdom would face divine retribution for his death.
Iran's Revolutionary Guards had promised "harsh revenge" against the Saudi Sunni royal dynasty for Saturday's execution of Nimr, considered a terrorist by Riyadh but hailed in Iran as a champion of the rights of Saudi Arabia's marginalized Shia minority.
Nimr, the most vocal critic of the dynasty among the Shia minority, had come to be seen as a leader of the sect's younger activists, who had tired of the failure of older, more measured leaders to achieve equality with Sunnis.
Although most of the 47 men killed in the kingdom's biggest mass execution for decades were Sunnis convicted of al Qaeda attacks in Saudi Arabia a decade ago, it was Nimr and three other Shias, all accused of involvement in shooting police, who attracted most attention in the region and beyond.
Following the attacks, Saudi Arabia has broken off diplomatic ties with Iran and recalled its diplomats from Tehran.
Iran is Saudi Arabia's main regional rival - they back opposing sides in the conflicts in Syria and Yemen.
Relations between the countries have been strained over various issues in recent decades, including
Iran's nuclear programme and deaths of Iranians at the Hajj pilgrimage in 1987 and again in 2015.
In such circumstance, US state department called upon the leaders across the region to take affirmative steps to calm tensions.
