Burundi's influential independent African Public Radio (RPA) station came under attack amid the confusion over the coup against President Pierre Nkurunziza.
The RPA station was hit by a rocket and set ablaze by pro-Nkurunziza police and ruling party youth, according to media boss and rights activist Innocent Muhozi.
RPA, which was closed by the government at the start of the anti-Nkurunziza protests, had only resumed broadcast a few hours earlier before it was bombed.
Several other radio stations were attacked overnight, hours after protesters torched Rema radio and television, which is associated with the ruling party.
"We condemn the attacks on media houses and they should let the media operate freely," said Mr Alexandre Niyungeko, the chair of the Burundi Journalists Union.
Mr Niyungeko pointed out that he did not know who attacked which stations, but regretted that they happened despite the army's promise of security everywhere.
Meanwhile, gun battles continued in the capital Bujumbura between those for and against the overthrow of President Nkurunziza.
The army in Burundi Wednesday announced a coup d'etat against President Nkurunziza's government.
General Godefroid Niyombare, a powerful former intelligence chief, announced the coup attempt on radio hours after the president left for a Burundi mediation summit in Tanzania.
President Nkurunziza, in a Twitter message, called for calm and said the situation in the country was under control.
However, the Burundi leader remains in Dar es Salaam after soldiers behind the coup announcement took over the airport and stopped him from flying back to the country after the aborted regional summit in Tanzania.
Laurent Kavakure, Burundi's Minister of Foreign Affairs said in Dar es Salaam that the "ousted" president would be going back to Burundi later on Thursday.
The minister spoke at Serena Hotel in Dar where the Burundi leader had also been accommodated after failing to fly back to Bujumbura.
Mr Kavakure did not say how the Mr Nkurunziza would get back to the crisis-torn country. The president's whereabouts on Thursday morning was not disclosed.
Tanzania's Foreign Affairs minister Bernard Membe separately told journalists he did not know where Mr Nkurunziza was.
The army is divided, with the coup plotters holding the airport while the Nkurunziza loyalists are reported to be in charge of the national radio and television.
Army Chief of Staff Maj-Gen Prime Niyongabo took to the national radio to condemn the coup.
"We are going to make sure that the army stays united and we will do our best to capture those who have declared a coup against President Nkurunziza," he said.
However, Maj-Gen Niyombare said troops under his command would seek to seize the broadcaster, seen as an important asset in mobilising national support.
"We didn't want bloodshed yesterday since it was still the first day, but what we can say is that soon we are going to attack the premises," said one of the army generals.
