Sydney doctor denies funding rebels

An Australian-based doctor who wants to stand as president of Uganda has denied as absolute nonsense allegations he is funding the assassination of Muslim clerics in his home country.

Sydney cardiologist Aggrey Kiyingi says the allegations are part of an orchestrated government harassment of his political organisation that has seen members imprisoned before the 2016 election.

Uganda's police chief, General Kale Kayihura, says the government might seek help from Interpol to arrest Dr Kiyingi in Sydney over his alleged involvement in rebel activities.

"It's absolute nonsense," Dr Kiyingi told AAP on Friday.

"(President Yoweri Museveni) has had to come up with his usual evil ways of trying to ban an opponent, so he made a pre-emptive strike and linked me to the murder of the Muslim clerics.

Several Muslim clerics have been killed or gone missing in Uganda in recent months.

Ugandan authorities have accused Dr Kiyingi of sponsoring the killings and funding the Allied Democratic Forces, a Muslim rebel group based in neighbouring Democratic Republic of Congo.

"I have no dealings with the ADF and I have never financed the ADF," Dr Kiyingi said.

"I condemn the killing of the clerics."

He says his supporters - who are campaigning by handing out business card-like "Kiyingi Cards" - have been harassed and arrested by authorities.

On January 17 police arrested Dr Kiyingi's chief mobiliser Aisha Nakasibante, 33, on charges of terrorism and murder.

"She was severely beaten, tortured and molested when she was abducted and for three days we did not know where she was," Dr Kiyingi said.

"She was robbed of money in her handbag, all her phones and the Kiyingi cards she was carrying were taken from her."

Dr Kiyingi provided a list of 17 other supporter workers he says have been arrested, beaten or tortured in recent months.

He has not been contacted by Ugandan or Australian authorities or Interpol since authorities started linking him last week to the killing of the clerics.

Over the past year relatives of Dr Kiyingi have been forcefully evicted from their homes in Uganda after a high court ruling in Kampala ordering his six properties be sold off to pay a $A1.3 million debt to a contractor he claims does not exist.

Dr Kiyingi was acquitted in 2006 on charges of orchestrating the shooting murder of his wife, Robinah - a high-profile lawyer revered for the human rights and corruption cases she pursued.

He moved to Australia from Uganda in the 1980s and still has a practice in Sydney's west.
