It was not immediately known if there were any casualties from the air raid, which the resident said destroyed an industrial site.

"It was heavy and the jet was so close," the resident said.

"It has burned the whole compound. We don't know the casualties but now the whole company is burned to ash."

On Monday, Ethiopia's air force carried out two air strikes against Tigray People's Liberation Front (TPLF) targets in Mekele, marking a sharp escalation in the nearly year-long conflict in the north of the country.

The United Nations said on Tuesday that those raids had killed three children and wounded nine people.

Prime Minister Abiy Ahmed's government appears to be pressing a new offensive against the TPLF, which dominated national politics for almost three decades before he took power in 2018.
