Seven men have been convicted of the murder of an award-winning environmental activist in Honduras. But has justice been done for Berta Cáceres? The Guardian’s Nina Lakhani explores what the case says about the state of modern Honduras. Plus: Mark Townsend on how easy it is to buy converted firearms in the UK

On 2 March 2016, a prominent environmental activist and campaigner for women’s rights, Berta Cáceres, was shot dead at her home in Honduras.

Last week seven men were found guilty of her murder at the end of five-week trial. The court ruled that the killing by a group of hitmen was ordered by executives of a company building a dam that she had protested against.

The Guardian’s Nina Lakhani describes how Cáceres’s murder, in a country where corruption is rife, attracted international attention. Honduras’s justice system has received millions in US and European aid, but the case was plagued by allegations of negligence, secrecy and bias.

Also today: how easy is it to buy a converted firearm in the UK? The Observer’s Mark Townsend on his investigation.

Nina Lakhani’s book on the life and death of Berta Caceres will be published by Verso Books in 2019
