Argentina Nisman death: Mass rally in rain

Hundreds of thousands of people have taken part in a march through the Argentine capital, Buenos Aires, to mark a month since the death of prosecutor Alberto Nisman.

Mr Nisman was found dead hours before he was due to testify against President Cristina Fernandez de Kirchner and her foreign minister.

He had accused President Fernandez of covering up alleged Iranian involvement in a bomb attack against a Jewish centre more than 20 years ago.
