A Russian couple was detained in Istanbul’s Hagia Sophia after being caught reading the Bible within the historic monument. Viktoria and Igor Filonova were arrested on Tuesday, according to Russian state news agency RIA Novosti. The Hagia Sophia, originally a cathedral, was converted into a mosque, a change which has sparked international debate. Despite its status change, the structure remains a significant historical and religious site for Christians. The couple’s arrest raises questions regarding religious freedom within the Hagia Sophia and the enforcement of rules for visitors. Details surrounding the specific charges and potential consequences for the couple remain unclear.
