A Bolivian radio journalist has been attacked while presenting his radio show in the city of Yacuiba, Bolivia.

Staff said that four men broke into the studio, poured petrol over Fernando Vidal, and set him alight, and eyewitnesses reported that the attackers had also thrown Molotov cocktails.

According to relatives, Mr Vidal, 78, was reporting on smuggling in the border area when the attack happened.

Mr Vidal suffered burns on his face, arms and chest.

His son-in-law, Esteban Farfan, said that Mr Vidal had been a harsh critic of the provincial government, voicing his criticism on air. Although Mr Farfan believes there are political motives for the attack as a result of his criticism, police have not yet commented on possible motives.
