Kebede Desisaa, the state communications minister, said the government had warned the US embassy and relevant agencies to continue spreading false information.
Kebede, who provided daily news to state media, said the agency had previously spread rumors that Addis Ababa was under siege and that this had now been replaced by other false information about the terrorist threat.
Ethiopian Prime Minister Abiy Ahmed has not been seen for two days after announcing three days ago that he had gone to the front lines. Abiy handed over the post of prime minister to Deneke Mokenen, the deputy prime minister.
The threat posed by the Ethiopian government to the US embassy cannot be taken lightly, according to commentators familiar with the narrow nature of Amhara politicians.
