Turkish police have used tear gas and rubber bullets to disperse people gathered for a gay-pride rally in Istanbul.
Authorities had banned the event, citing security concerns, but many say the crackdown symbolises Turkey's drift towards authoritarianism under President Recep Tayyip Erdogan.
Pride marches are intended to celebrate difference and encourage tolerance.
But hundreds of Turkish police, brandishing riot shields, have again thwarted an attempt to hold a gay-pride parade in Istanbul, blocking roads and arresting people on the street.
Istanbul's governor had banned the event for the third straight year, citing security concerns from nationalist groups.
But this activist says she suspects the crackdown has much more to do with President Erdogan's desire to appease Turkish conservatives.
"I think it's nonsense. Everybody deserves equal rights. Equal rights is not a pie that, if you give some part of it, you don't lose yours. So we all deserve equal rights, and we all need equal rights."
Turkey was once considered far safer for gay people than many other countries in the Middle East.
For more than a decade, Turkey's Pride March had been held peacefully, attracting tens of thousands of people.
Unlike many Muslim-majority nations, homosexuality is legal in Turkey.
But homophobia remains widespread.
And President Erdogan and his AK Party appear have shown little interest in expanding rights for minorities, gays and women.
Seyhan Arman, a transgender woman, said before the parade that the government's approach worried her.
"The fact that the existing government is not making necessary changes to the constitution in favour of LGBTI individuals and the fact that there is negative discourse against us may encourage people who are already trans-phobic."
Mr Erdogan won a referendum in April that granted him sweeping new powers.
Dr Murat Yurtbilir, from the Australian National University's Centre for Arab and Islamic Studies, says there is potential for his government to wield its powers even more forcefully.
"The LGBTI and such kinds of movements, different ethnic movements or different identity movements, they were gaining ground in the 1990s, early 2000s. That now is totally reversed. Their rights are getting less, and the police brutality is increasing, unfortunately."
The pride-event organisers say at least 41 people have been detained.
