President Xiomara Castro’s government must do more to protect those fighting for environmental rights, critics say.

The killing of two Honduran water defenders this month has sparked international outrage, with the United Nations calling for an investigation

and locals questioning the government’s commitment to protecting environmental activists. Reinaldo Dominguez, Aly’s brother, said that the killing capped off a long process of intimidation.

Aly Dominguez, 38, and Jairo Bonilla, 28, were members of the Guapinol water defenders movement, organising to protect their rivers

from a controversial open-pit iron oxide mining project in Carlos Escaleras National Park. Several activists have been killed in unclear circumstances amid community opposition to the mine.

The families of Dominguez and Bonilla say they were killed by unidentified gunmen after weeks of threats related to their activism.

Upon taking office a year ago, Honduran President Xiomara Castro promised to undo more than a decade of corruption since the 2009 coup against her husband, former President Manuel Zelaya.
