The BBC is reporting this breaking news, so check back there for updates:
Police in Bangladesh say two people including a leading gay rights activist and editor at Bangladesh’s only LGBT magazine have been hacked to death.
The US ambassador to Bangladesh condemned the killing of Xulhaz Mannan, who also worked at the US embassy.
Another person was also injured when the attackers entered a Dhaka flat.
Since February last year suspected militants have killed several secular or atheist writers and members of religious minority groups.
The two men were murdered two days after a university teacher was hacked to death by suspected Islamist militants.
So-called Islamic State (IS) claimed responsibility – but the Bangladeshi government insists there is no IS presence in the country.
“I am devastated by the brutal murder of Xulhaz Mannan and another young Bangladeshi,” said US Ambassador Marcia Bernicat.
“We abhor this senseless act of violence and urge the Government of Bangladesh in the strongest terms to apprehend the criminals behind these murders,” she added.
BBC Bengali Service editor Sabir Mustafa said staff at Roopbaan, which had not been condemned by the government and received some support from foreign embassies, had been careful to protect their identities but had not believed their lives were at risk.
Suspected extremists in Bangladesh are gaining a sense of security that they can carry out killings with impunity, he says.
A British photographer who knew Mr Mannan and the other victim, known as “Tonoy” and named in Bangladeshi media as Tanay Mojumdar, said they and other friends had set up Roopbaan with the aim of spreading tolerance.
Both men were openly gay and believed that if more gay Bangladeshis came out then the country would have to accept them, the photographer said.
This is yet another travesty for progressive existence in a country blighted by terrible, terrible extremism.
When will this stop?
