Honduran police have arrested three men for the murder of Lesbia Urquia, an environmental activist who fought against hydroelectric and mining projects on indigenous lands in the Central American country, authorities said on Wednesday, according to Reuters. Urquia, a colleague of slain Honduran activist Berta Caceres, was found dead with wounds to her head a week ago in the town of Marcala, 62 miles (100 km) west of Tegucigalpa. "Three men suspected of the crime have been arrested, including a brother-in-law of the deceased," said Jorge Galindo, a spokesman for the attorney general's office. The brother-in-law, Manuel Lopez, had threatened to kill Urquia, 49, over a family dispute involving property and was suspected of hiring the other two men to carry out the crime, Galindo said.
