An explosion struck a residential building in the Iranian port city of Bandar Abbas, resulting in the death of a minor girl and causing damage to an eight-storey structure and homes nearby, Fars News Agency reported on Saturday.

According to Fars, citing provincial crisis management officials, emergency and operational teams were dispatched immediately after the explosion, and the injured were transferred to medical centres.

As per Fars, the cause of the explosion was not immediately clear.

CNN reported that a US official told CNN the explosion was not related to any US military action, and an Israeli official said Israel was not involved either.

The blast comes amid heightened tensions in the region after US President Trump hinted warned towards a possible military action against Iran.
