A large explosion was heard in Iran's capital on Saturday, according to the Iranian Fars News agency.Later reports indicated that the explosion was caused by a stun grenade - a device which explodes with bright light and a loud sound - which had been set up to go off in a park near an adjoining hospital building, a TV reporter said.
Tehran Deputy Governor Hamid Reza Goudarzi, who is in charge of security issues in the city, visited the site.
"Just one explosion took place inside Mellat (People) Park," he told the semi-official Tasnim news agency.Asked whether the incident was an attack, Goudarzi said: "We are investigating the dimensions and causes of the incident and we will provide information after we are sure."
Deputy Security Chief for Tehran Province Hamidreza Goudarzi has been quoted by the IRGC-affiliated Tasnim News as saying that the incident is under investigation, it was unclear at this time what caused it, and it is unknown whether or not it was an act of terrorism. Iranian media has reported that there were no casualties at the scene.The explosion happened several hours after a large-scale cyberattack across Iran, with hackers posting the phone number of the country's supreme leader as the number to call for information for train delays.
