Protesters in Iran have set fire to the ancestral home of the founder of the Islamic Republic, Ayatollah Ruhollah Khomeini.
Images posted on social media show part of the structure in the city of Khomein being set ablaze.
News agencies have verified the videos' location, but regional authorities denied there had been an arson attack.
Ayatollah Khomeini is said to have been born in the house, which is now a museum that commemorates his life.
Khomeini was the leader of Iran's Islamic revolution in 1979, which deposed the country's pro-Western leader, Shah Mohammad Reza Pahlavi, and ushered in the theocratic state that still exists today.
He served as the first supreme leader of Iran until his death in 1989, which is still marked by a day of mourning each year.
Social media videos from Khomein show dozens of people cheering as the fire breaks out. An activist network said the footage was taken on Thursday evening.
However, Khomein county's press office denied there had been any attack to the semi-official Tasnim news agency.
The agency said a small number of people had gathered outside the house and later shared a video of the house, saying it was open to "pilgrims and lovers of the deceased Imam".
"The doors of the house of the late founder of the great revolution are open to the public," the agency added.
Protestors in the city of Khomein have burned down the childhood home of the late Ayatollah Khomeini, founder of the country's current theocracy. The symbolic significance of this move against the most revered figure in the Islamic Republic cannot be overstated.#MahsaAmini pic.twitter.com/vmoJfj3NAX
The fire at his ancestral house is one of the latest incidents in a wave of nationwide demonstrations directed at his successor, Ayatollah Ali Khamenei, and his government.
The protests against Iran's clerical establishment erupted two months ago after the death in custody of Mahsa Amini, a 22-year-old woman who was detained by morality police for allegedly breaking the strict hijab rules.
Five members of the security forces were killed in the latest unrest on Thursday, according to Iranian state media.
Meanwhile, funerals for young Iranians said to have been killed by security forces sparked fresh demonstrations on Friday.
Crowds chanting "death to Ali Khamenei" gathered in the south-western city of Izeh for the funeral of a nine-year-old boy, Kian Pirfalak, who was shot dead by security forces, according to his family, although officials have denied this.
There were further protests in the cities of Tabriz, Mahabad and Zahedan over civilian deaths blamed on security forces.
