Anti-regime protesters set fire to Khomeini's ancestral home in Iranian city of Khomein

Protesters in Iran have set on fire the ancestral home of the Islamic republic's founder Ayatollah Ruhollah Khomeini as two months of anti-regime demonstrations show no letup, images showed on Friday.

The house in the city of Khomein in the western Markazi province was shown ablaze late Thursday with crowds of jubilant protesters marching past, according to images posted on social media, verified by AFP.

Khomeini is said to have been born at the house in the town of Khomein -- from where his surname derives -- at the turn of the century.

He became a cleric deeply critical of the US-backed shah Mohammed Reza Pahlavi, moved into exile and then returned in triumph from France in 1979 to lead the Islamic revolution.

Khomeini died in 1989 but remains the subject of adulation by the clerical leadership under his successor Ayatollah Ali Khamenei.

The house was later turned into a museum commemorating Khomeini. It was not immediately clear what damage it sustained.

But Iran's Tasnim news agency later denied there had been a fire, saying the "door of the historic house is open to visitors".

"The counter-revolutionary media tries to create turmoil by spreading lies and false information. The burning down of Imam Khomeini's historic house, a place with with spiritual value to Iranians, was one of those lies," the deputy goveronor of Markazi province Behnam Nazari was quoted as saying.

The protests sparked by the death of Mahsa Amini, who had been arrested by the morality police, pose the biggest challenge from the street to Iran's leaders since the 1979 revolution.

They were fuelled by anger over the obligatory headscarf for women imposed by Khomeini but have turned into a movement calling for an end to the Islamic republic itself.

Images of Khomeini have on occasion been torched or defaced by protesters, in taboo-breaking acts against a figure whose death is still marked each June with a holiday for mourning.
