Iran's 20 years of revolution
Towns and cities across Iran have been bedecked with the Ayatollah's image
Iran has been commemorating the day 20 years ago when Ayatollah Khomeyni returned in triumph after 15 years in exile to take control of the Islamic revolution which unseated the Shah.
Iranian television repeatedly showed archive film of the tumultuous scenes which followed the Ayatollah's return.
He made his way through packed streets to the Behesht-e-Zahra Cemetery on the outskirts of Tehran where he made his first speech before taking up leadership of the forces that brought down the Shah's regime.
At the memorial ceremony, one of the Ayatollah's close companions, the former president, Hashemi Rafsanjani, paid glowing tribute to the charismatic cleric who provided the focal point for the national uprising against the Shah.
For all Iranians, this will be an occasion to contemplate the changes that the last 20 years have brought.
But the anniversary comes at a time when there is a power struggle power between reformists and hardline conservatives going on in Iran over which direction the country and the revolution should take in a rapidly changing world.
Explosions cloud mood
On the eve of the anniversary, a number of explosions were reported near the intelligence ministry compound on the outskirts of the capital.
The official Iranian news agency said windows had been broken and several cars damaged in what it described as a failed attack by the People's Mujahadeen, an armed opposition group based in Iraq.
Meanwhile, some agents of the Intelligence Ministry have been arrested for alleged involvement in the recent killings of liberal writers and intellectuals.
In the current climate, it is not clear whether the attempted attack on the ministry was connected with that situation or, as the authorities suggest, a provocation staged by enemies of the Islamic regime.
