During the festivities -- held on the last Tuesday eve before the Iranian New Year, which falls on March 20 -- people leap over fires to 'purify' themselves and banish evil spirits ahead of the year to come.

Tehran police chief Mohsen Ansari, cited by state radio, said those found making firecrackers and other explosive devices would be arrested as authorities try to cut down on potential injuries.

But unlike previous years, small fireworks have been openly available on street corners throughout the Iranian capital.

State television said Monday that 17 young people have been injured in recent weeks in explosives-related incidents.
