Suspected Islamist militants hacked to death a leading Bangladeshi gay rights activist employed by the U.S. embassy and a friend in an apartment in Bangladesh's capital on Monday, police said.
The killings took place two days after a university professor was slain in similar fashion on Saturday in an attack claimed by Islamic State.
Five or six assailants went to the apartment of Xulhaz Mannan, 35, an editor of Rupban, Bangladesh's first magazine for gay, bisexual and transgender people, and attacked him and a friend with sharp weapons, Dhaka city police spokesman Maruf Hossain Sordar said.
They entered the apartment disguised as couriers, he said, quoting witnesses.
The assailants also wounded a security guard. Witnesses said the attackers shouted "Allahu Akbar" ("God is greatest)" as they fled the scene.
Mannan was employed by the U.S. embassy, working for the U.S. Agency for International Development, the State Depertment in Washington said.
State Department spokesman John Kirby said the United States was "outraged" by the "barbaric attack." He called Mannan, "a beloved member of our embassy family and a courageous advocate for LGBTI rights - human rights, actually."
"LGBTI" stands for lesbian, gay, bisexual and intersex.
A spokesman for the White House's National Security Council, Ned Price, said the United States strongly urged the Bangladeshi government to ensure the perpetrators were brought to justice.
Other attacks took place in the country on Monday, but it was not immediately clear whether those assaults were carried out by Islamist militants.
