PORT-AU-PRINCE, July 10 (BBC) - The injured widow of Haiti's president has described the moment assassins "riddled" her husband with bullets after bursting into their home in the middle of the night.

Martine Moïse said the attack happened so quickly, her husband Jovenel was unable to "say a single word".

President Moïse was killed on 7 July, allegedly by 28 foreign mercenaries.

Mrs Moïse was also injured in the attack, and was flown to Miami for treatment.

On Saturday, she posted a voice message to her Twitter page vowing to continue his work. A number of people have confirmed it is the president's wife.

"In the blink of an eye, the mercenaries entered my house and riddled my husband with bullets," Mrs Moïse says in the recording, describing the moment the attackers killed her husband.

"This act has no name because you have to be a limitless criminal to assassinate a president like Jovenel Moïse, without even giving him the chance to say a single word," she continued.

She suggested her husband was targeted because for political reasons - in particular, mentioning a referendum on changes to the constitution which could have given the president more power.

The unnamed people, she said, "want to assassinate the president's dream".

"I am crying, it is true, but we cannot let the country lose its way," she added. "We cannot let the blood of President Jovenel Moïse, my husband, our president whom we love so much and who loved us in return, flow in vain."
