Argentina cover-up claim prosecutor found dead
An Argentine federal prosecutor who accused President Cristina Fernandez de Kirchner last week of a cover-up has been found dead at his home in the capital, Buenos Aires.
Alberto Nisman was investigating the 1994 bombing of a Jewish centre in Buenos Aires in which 85 people died.
On Wednesday, he accused the president of involvement in a plot to cover up Iran's alleged role in the bombing.
The BBC's Ignacio de los Reyes says a weapon was found next to Mr Nisman's body, but the circumstances surrounding his death remain a mystery.
