A retired British banker is facing up to seven years in jail in Uganda after he was charged with gross indecency.
A UK theatre producer fears a case in which he was charged over a gay play could yet be reopened if the state 'produces more evidence'.
Uganda may be one of the worst places in the world to be gay. But a new bill being considered by Parliament could make it even worse.
The World Bank has suspended a $90 million (£54m) loan to Uganda over its anti-gay law.
President Yoweri Museveni signed a bill on Monday which calls for life imprisonment for those caught having gay sex.
The decision sparked condemnation from western governments and human rights, with Foreign Secreatry William Hague saying he was "deeply saddened and disappointed" by the move.
A spokesman from the bank said the loan was intended to help the east African nation strengthen its health systems, and it wanted to ensure that the development objectives of the project would not be affected by the controversial new law.
A Ugandan tabloid has published a list of what it called the country's "200 top" homosexuals the day after the country's president signed an anti-gay law.
The Red Pepper newspaper published the names, and some pictures,in a front-page story under the headline: EXPOSED!
The list included prominent Ugandan gay activists such as Pepe Julian Onziema, who has repeatedly warned that Uganda's new anti-gay law could spark violence against homosexuals.
ITV News' Africa correspondent, Rohit Kachroo, tweeted that Amnesty has called the list 'chilling'.
A day after Uganda's president signs anti-gay bill, local tabloid prints list of 200 gay Ugandans. Amnesty calls it 'chilling'
Ugandan president Yoweri Museveni enacted a bill on Monday that punishes gay sex with up to life in jail - a measure criticised as draconian in a country where homosexuality had already been criminalised.
A spokesman for Ugandan police Patrick Onyango said no homosexuals have been arrested since Museveni signed the bill.
Gay and lesbian organisations fear the Ugandan anti-gay bill will encourage other governments to strengthen penalties, increase harassment, discourage people from taking HIV tests and make it impossible to live an openly gay life.
"Clawing back these basic rights and criminalising the expression of divergent views doesn't bode well for anyone in Uganda," said Maria Burnett of Human Rights Watch.
Deputy Prime Minister Nick Clegg has branded Uganda's anti-gay bill as an "abhorrent backwards step for human rights".
The Ugandan anti-gay law is an abhorrent backwards step for human rights. It should never be a crime to be LGBT.
Foreign Secretary William Hague has said he was "deeply saddened and disappointed" by Uganda's decision to extend the ban on homosexuality.
The bill, which was signed into law by President Yoweri Museveni, calls for first-time offenders to be sentenced to 14 years in prison and makes it a criminal offence not to report someone for being gay.
He said: "The UK strongly opposes all discrimination on any grounds. We question the Bill's compatibility with Uganda's constitution and international treaty obligations.
"There can be no doubt that this Bill will increase persecution and discrimination of Ugandans, as well as damage Uganda's reputation internationally."
Homosexuality is already a criminal act in Uganda and the new bill is set to recommend a term of life imprisonment for those found guilty of "aggravated homosexuality", defined as repeated gay sex between consenting adults.
Before signing in the anti-gay laws, Ugandan President Yoweri Museveni said that he was privy to scientific "facts" saying: "No study has shown you can be homosexual by nature."
Ugandan President Yoweri Museveni has said "you can come back with worms" after engaging in gay sexual acts as he claimed the nation's anti-gay legislation that will see repeat 'offenders' locked up for life is backed by scientific "facts".
Mr Museveni, a devout evangelical Christian, said homosexuals were "heterosexual people" who act as "prostitutes because of money" in an astonishing statement deliberately intended as a rebuke of "Western countries".
He said he had received scientific "facts" before signing in the anti-gay laws, saying: "No study has shown you can be homosexual by nature."
He said homosexuality in Uganda has been "provoked by the arrogant and careless Western groups that are coming in our schools and recruiting homosexuals into homosexuality and lesbianism".
Mr Museveni also issued a sharp warning to outside nations not to interfere on the matter.
"I would advise Western countries, this is a no-go area," he said. "I don't mind being in a collision course with the West. I am prepared."
In a statement by Desmond and Leah Tutu, the pair said they were "disheartened" by Ugandan President Yoweri Museveni's decision to sign an anti-gay bill.
The statement reads: "When President Museveni and I spoke last month, he gave his word that he would not let the Anti-Homosexuality Bill become law in Uganda. I was therefore very disheartened to hear last week that President Museveni was re-considering his position...
"We must be entirely clear about this: The history of people is littered with attempts to legislate against love or marriage across class, caste and race. But there is no scientific basis or genetic rationale for love. There is only the grace of God.
The statement added: "There is no scientific justification for prejudice and discrimination, ever. And nor is there any moral justification. Nazi Germany and apartheid South Africa, among others, attest to these facts."
Ugandan President Yoweri Museveni has signed into law an anti-gay bill that toughens already strict legislation against homosexuals.
The move defies warnings from the United States that relations could be complicated by the new rules.
Museveni's signature will please a staunchly conservative local constituency that is vehemently opposed to homosexuality, but risks alienating Western aid donors.
The new bill punishes anyone convicted of having gay sex with jail terms up to life, according to a draft of the legislation.
It also makes it a crime to fail to report someone for breaking the new law, again according to drafts.
Museveni signed the bill during a press conference at State House in Entebbe, close to the capital Kampala.
Uganda's President Yoweri Museveni is expected to sign a controversial anti-homosexuality today that allows harshers penalties in a country where homosexuality is already a crime.
A Ugandan government spokesman told Reuters that the president would be signing the bill to "demonstrate Uganda's independence in the face of Western pressure and provocation".
The law punishes first-time "offenders" with 14 years in prison, with life imprisonment the penalty for "aggravated homosexuality".
The president's decision to sign the bill comes less than a week since he put the bill on hold to give scientists a chance to prove that homosexuality could be triggered by genes and is not a "lifestyle choice".
President Obama warned Museveni that he would "complicate" US relations if he signed the bill.
