(CNN) -- Suicide bombings outside the Imam Hussein Mosque in Chabahar in southeastern Iran killed at least 38 people and injured dozens more Wednesday, state-run news agencies reported.
The Red Crescent relief agency told the semi-official ISNA news agency that the toll could rise.
Mohammad Yaghoub Jedgal, a deputy with the Chabahar parliament, told the IRNA news agency that about 50 to 60 victims had been rushed to medical centers for treatment.
The governor of Chabahar said a suspect has been taken into custody.
"The main perpetrator of the terrorist attack, which has killed and wounded a number of Iranians, has been arrested," Gov. Ali Bateni told IRNA.
The violence comes as Shiite Muslims across the world are observing a period of mourning commemorating the martyrdom of Imam Hussein, the prophet Mohammed's grandson and one of Shiite Islam's holiest figures. CNN
