Jaish al-Adl armed militants claimed responsibility for an explosion that destroyed the Housing Foundation headquarters in Chabahar in southern Sistan and Baluchestan province on Saturday.
The group said it was a response to government-led demolitions of homes in the region to expand the Makran coast.
The group announced on social media that its members entered the building, evacuated staff and visitors, and then detonated explosives.
Zahedan’s prosecutor, Mehdi Shamsabadi, said a sound bomb exploded at the Coordination Office for Eastern Chabahar Villages, partially destroying the site.
“Security and intelligence forces are investigating those responsible, and the necessary judicial orders have been issued,” he said.
No casualties were reported.
Iran’s state broadcaster, IRIB, reported that armed individuals stormed the office, forced people out, and then set off explosives.
Jaish al-Adl said the attack was part of its “commitment to holding government offices accountable” for their role in displacing the Baloch population.
The group has carried out multiple attacks on security forces in Sistan and Baluchestan in recent years.
In November, four members of the Islamic Revolutionary Guard Corps were killed in clashes during a military drill in Rask County.
Jaish al-Adl also claimed responsibility for an attack in October that left ten Iranian military personnel dead.
Both Iran and the United States have designated Jaish al-Adl as a terrorist organization.
The group has accused the government of demographic engineering in the Makran coast development project, saying the project undermines the cultural and religious identity of the region’s Baloch residents.
Over the past two decades, Valentine’s Day has grown increasingly popular in Iran, frustrating authorities who have spent nearly half a century trying to Islamicize society and shield young people from Western cultural influences.
In 2010, Iran’s police and judicial authorities condemned Valentine’s Day celebrations as part of a “Western cultural onslaught”, imposing a ban on businesses selling Valentine’s Day gifts and decorations.
Since then, police have occasionally cracked down on shops selling gifts and cafés hosting Valentine’s celebrations, where young people gather with red balloons, roses, teddy bears, and other tokens of affection. Despite these efforts, Valentine’s Day has continued to gain popularity, even spreading to religious cities such as Qom and Mashhad, home to two of Shiism’s most important shrines and seminaries.
A call to revive Sepandarmazgan
Beyond government opposition, some Iranians also criticize the growing influence of Western holidays, advocating for the revival of ancient Iranian festivals instead. They argue that Sepandarmazgan, or Espandgan for short, offers a more culturally authentic alternative to Valentine’s Day.
Falling on February 23 this year, Sepandarmazgan is dedicated to Sepandarmaz (Holy Devotion), one of the seven divine entities emanating from Ahura Mazda, the Zoroastrian creator god.
In ancient Iranian tradition, Sepandarmaz was revered as a feminine divine force linked to the Earth and women, symbolizing fertility and prosperity. Unlike Anahita—an earlier goddess of love, fertility, and water whose worship was later absorbed into Zoroastrianism—Sepandarmaz was never portrayed in human form in ancient artifacts.
Sending text messages and giving gifts to loved ones on Espandgan instead of Valentine's Day has been gaining popularity in recent years.
According to a recent article published by the Student News Network, a hardline news outlet, presenting Espandgan as an alternative to Valentine’s Day fails to prevent the spread of Western cultural values. Instead, it merely repackages the same concepts in a form that contradicts the Islamic way of life.
Espandgan in history and modern Zoroastrianism
Iran’s Zoroastrian community, though now small, continues to celebrate Espandgan with solemn religious rituals and prayers, including recitations from the Avesta—their holy book—at fire temples and sacred shrines, such as Pir-e Sabz in Yazd.
According to the 11th-century historian Al-Biruni, however, Espandgan was widely observed in parts of Iran as a day honoring women. On this occasion, women were exempt from housework, and men showered their wives with gifts. Additionally, women freely expressed their love to the men they wished to marry, a tradition that resonates with modern romantic celebrations.
Government opposition to pre-Islamic traditions
Despite the historical significance of Espandgan, Iran’s religious and political establishment remains resistant to promoting pre-Islamic festivals as substitutes for Western celebrations like Valentine’s Day and Christmas—both of which remain widely celebrated despite official disapproval.
In recent years the celebration of Christmas has also become very popular in Iran.
Beyond Valentine's Day, the hardline religious and political establishment also opposes other ancient festivals including the Winter Solstice festival of Yalda (or Shab-e Chelleh) which marks the longest night of the year, and Charshanbeh Soori, a bonfire festival held on the evening of the last Tuesday before the Iranian New Year (Nowrouz) as relics of paganism.
Charshanbeh Soori often turns into a battle between the merry-making youth who celebrate it on the streets and the police, Basij militia of the Revolutionary Guards, and vigilante groups who crack down on them in larger cities such as Tehran.
In an attempt to counter pre-Islamic traditions and calendar events, authorities have sought to elevate Islamic occasions, designating the birthday of Fatima, daughter of Prophet Muhammad, as Women’s Day. The birthday of Imam Ali, the first Shiite Imam, has similarly been designated as Men’s Day while the anniversary of Fatima and Ali’s marriage has been added to the official calendar as Marriage Day.
