The ceremonies took place on Saturday and Sunday, on the occasion of the martyrdom anniversary of Hazrat Fatima Zahra (PBUH), the daughter of Islam’s Prophet Muhammad (PBUH), Press TV reported.
The funerals were held in the cities of Neyshabur, Yazd, Bafq, Birjand, Tehran, Larestan and Isfahan.
Among the martyrs laid to rest, 12 were unidentified.
Additionally on Sunday, the remains of 55 newly-recovered martyrs were returned to Iran from the Shalamcheh border crossing with Iraq.
They will be transferred to the southwestern city of Ahvaz and then to Tehran for identification.
Supported by major Western and regional states, former Iraqi dictator Saddam Hussein launched a massive invasion in 1980 in a bid to seize Iran's resource-rich Khuzestan Province, less than two years after the Islamic Revolution.
With the army mostly in disarray, Iranians closed ranks under the leadership of the late founder of the Islamic Republic Imam Khomeini as they rushed to the warfronts to push back Iraqi forces and liberate occupied territories.
The war ended in 1988 with a cease-fire deal, with the Iraqi dictator failing to achieve any of his goals and Iran not conceding an inch of its territory.
Over the years, the Islamic Republic and Iraq have carried out numerous search operations to recover the remains of their fallen soldiers.
