An apparent explosion in southern Damascus this morning in which a busload of Iranian pilgrims were reportedly involved was an accident and not a terrorist attack, Syria's interior minister said.
Three people however died in the incident at a filling station, Said Mohammad Sammour said.
Sammour said the three - the Iranian bus driver and two Syrian filling station workers - were killed when a tyre they were pumping air into exploded.
“There were no explosives involved” in the accident he said, adding there were no pilgrims nearby when the explosion occurred.
The incident happened in the Sayyida Zainab suburb of the Syrian city.
The suburb is popular with Iranian and other Shiite pilgrims and is the location of a shrine dedicated to the granddaughter of the Prophet Muhammad.
