Rockets have been fired from the restive Tigray region of Ethiopia across the border at the capital of Eritrea, local media and diplomats say.
Explosions were heard in Asmara as several rockets landed on the outskirts of the city but there were no immediate reports of injuries.
Tigray’s ruling party, which is locked in a conflict with Ethiopia’s federal government, had threatened an attack.
The party’s forces fired rockets earlier at another region of Ethiopia.
The Tigray People’s Liberation Front (TPLF) said it had targeted two sites in the Amhara region on Friday and warned of further strikes.
Tension between the TPLF and the federal government escalated over the past month.
Eritrea fought a bloody war with Ethiopia two decades ago with final peace only agreed in 2018.
Fighting over Tigray has also affected Sudan, with at least 17,000 civilians crossing the border from Ethiopia, according to the UN.
What happened in Eritrea?
On Saturday night, residents of Asmara reported hearing loud explosions.
“The reports we’re getting indicate that several of the rockets hit near the airport,” an unnamed diplomat told AFP news agency.
Eritrea’s semi-official Tesfa News website tweeted that two rockets fired from TPLF-held territory in Tigray had missed the airport and landed on the outskirts of the city.
A TPLF spokesman had earlier threatened missile strikes against Eritrea, having accused its forces of crossing into Ethiopia to back federal forces there.
The Eritrean government has denied any role in the conflict but the BBC’s Africa regional editor, Will Ross, says reports of fighting along the border, and of soldiers being treated in Eritrean hospitals, suggest the opposite is true.
