Hundreds of journalists for Voice of America (VOA) - most of its remaining staff - have been fired by President Donald Trump's administration, effectively shutting down the US-funded news outlet.

The Trump administration, which has long accused VOA of left-wing bias, said the layoffs were because the agency was "riddled with dysfunction, bias and waste".

Steve Herman, VOA's chief national correspondent, called the dismantling of the outlet, which was set up during World War Two to counter Nazi propaganda, a "historic act of self-sabotage".

Among those axed were Persian-language reporters who had been on administrative leave, but were called back to work last week after Israel attacked Iran.

According to the Associated Press news agency, the Persian reporters had left the office on Friday for a cigarette break, and were not allowed to re-enter the building after the termination notices went out.
