According to the director of a local hospital, an air attack on Friday in the capital of Ethiopia's northern Tigray province claimed at least four lives, two of them being children.
The strike in Mekelle began about 09:40 GMT, according to Tigrai Television, which is under the jurisdiction of the local authorities, and the federal government was to blame. There are no other known military aircraft flying in Ethiopian airspace.
Following that, the Ethiopian government warned Tigrayans to avoid military and training sites, announcing in an online statement that it will "take actions to target the armed forces."
Legesse Tulu, a spokesman for the federal government, and Colonel Getnet Adane, a spokesman for the military, both declined to comment on the air strike, which occurred days after violence erupted on the border between the Tigray and Amhara provinces between the national government and Tigray troops.
The strike, according to Kibrom Gebreselassie, CEO of Ayder Hospital, also affected a playground for kids. It wasn't readily obvious if there were any neighbouring military installations.
He showed pictures of the dead and injured. Images of damaged structures and what appeared to be injured individuals lying on the ground receiving medical attention were shown on Tigrai Television.
A humanitarian source in the city confirmed hearing an explosion and anti-aircraft gunfire.
Kibrom said on Twitter that the hospital had received four dead from the strike, two of them children, and nine others were admitted with wounds.
Reuters could not independently verify his account.
Both sides have blamed each other for breaking a four-month-old ceasefire between Prime Minister Abiy Ahmed’s government and the Tigray People’s Liberation Front (TPLF), the party that controls Tigray.
War erupted in Tigray in November 2020 and spread to the neighbouring regions of Afar and Amhara a year ago. Last November, Tigrayan forces marched towards Addis Ababa, but were driven back by a government offensive that month.
A ceasefire was announced in March after both sides fought to a bloody stalemate and the government declared a humanitarian truce, allowing badly needed food aid into the region.
The fighting has displaced millions of people, pushed parts of Tigray into famine conditions and killed thousands of civilians.
The vast majority of residents of Tigray have had no access to telephone or internet service for more than a year.
