TEHRAN - The Iranian Foreign Ministry on Tuesday summoned Canberra’s ambassador to Tehran to strongly protest the posting an offensive content on the Australian embassy’s official Instagram page a day earlier.

The director general of the ministry’s Regional Department strongly condemned the publishing of the “norm-breaking” content, saying the "offensive " content published is “against Iranian and Islamic tradition, norms and culture,” Press TV reported.

The ministry official stated that such an action must not be repeated, calling it a violation of international law and the 1961 Vienna Convention on Diplomatic Relations.

The history of Iran's foreign relations shows the high sensitivity of the public opinion and their reaction to such content that violates norms, the ministry said.

Ambassador Ian McConville said the Australian embassy surely did not intend to offend the people and values ??observed by the Iranian society and that the Islamic Republic was not mentioned in the message.

The ambassador said he will convey Iran’s protest to his respective country.

The Australian embassy in Tehran published a post on its official Instagram page which promoted homosexuality.

"Celebrating 'Wear it Purple Day' with a splash of purple in every corner, and some delicious cupcakes made with love," the embassy wrote, expressing dedication to creating "a supporting environment where everyone, especially LGBTQIA+ youth, can feel proud to be themselves".

"Wear Purple Day" is named for homosexuality support in Australia. However, the Australian embassy in Tehran, regardless of the customs and beliefs of the people of Iran, has promoted this immoral issue by using purple symbols and holding a ceremony.
