There was also no immediate information on casualties in either Mai Tsebri or Adwa
Ethiopia's military on Sunday launched two air strikes on what a government official said were rebel-held facilities in Tigray, the seventh and eighth bombardments in its war-torn northern region in a week.
The strikes, far from the regional capital Mekele, signalled the military was potentially widening its campaign of aerial bombardments which has drawn international rebukes and disrupted UN flights to the famine-threatened region.
"Today the western front of (Mai Tsebri) which was serving as a training and military command post for the terrorist group TPLF has been the target of an air strike," government spokeswoman Selamawit Kassa said, referring to the Tigray People's Liberation Front (TPLF).
Later, Selamawit said the same mission destroyed a separate facility in the northern town of Adwa used to manufacture "military equipments" as well as fake military uniforms used by TPLF combatants.
There was no immediate response from the TPLF, which has condemned earlier strikes as evidence of the government's disregard for civilian lives.
There was also no immediate information on casualties in either Mai Tsebri or Adwa.
Prime Minister Abiy Ahmed's government has been locked in a war against the TPLF since last November, though Tigray itself had seen little combat since late June, when the rebels seized control of much of Ethiopia's northernmost region and the military largely withdrew.
But on last Monday Ethiopia's air force launched two strikes on Tigray's capital Mekele that the UN said killed three children and wounded several other people.
Since then, there have been three more strikes on Mekele and another targeting what the government described as a weapons cache in the town of Agbe, about 80km to the west.
The strikes coincide with ramped-up fighting in Amhara region, south of Tigray. They have drawn rebukes from Western powers, with the US last week condemning "the continuing escalation of violence, putting civilians in harm's way."
UN suspends flights
A strike on Friday on Mekele forced a UN flight carrying 11 humanitarian personnel to turn back to the Ethiopian capital Addis Ababa, and the UN subsequently announced it was suspending its twice-weekly flights to the region.
TPLF spokesman Getachew Reda on Friday criticized the air force for putting the UN flight at risk.
"Our air defense units knew the UN plane was scheduled to land & it was due in large measure to their restraint it was not caught in a crossfire," Getachew said on Twitter.
The TPLF issued a statement on Saturday saying the incident revealed the government's "intention to continue obstructing humanitarian operations."
The conflict has spurred fears of widespread starvation, as the UN estimates it has pushed 400,000 people in Tigray into famine-like conditions.
