Satellite images have given a rare glimpse into the resurgence of fighting in Ethiopia's northern Tigray region, one of the world's most hidden conflicts, where communications have been cut off and journalists denied permission to visit.
The images taken this month show the build-up of troops and military hardware along Ethiopia's border with Eritrea, which backs Prime Minister Abiy Ahmed against the Tigray People's Liberation Front (TPLF), the group that controls the region.
Eritrea recently mobilised its reserve forces for a reported offensive in Tigray.
Fighting reignited in August after a five-month humanitarian ceasefire broke down.
The United Nations' World Food Programme estimates that 13 million people need aid across northern Ethiopia because of the civil war.
These first images are taken from the north-western town of Sheraro, which had been in the hands of Tigrayan forces.
The image above shows the main road leaving the town heading east.
Tanks are positioned on the main road in the bottom left. To the right lies the Maiani Hospital, which opened in 2014 with surgical rooms, an obstetrics department, X-ray facilities and 35 beds.
What appears to be about 150 people, probably fighters, are organised in a formation or queue stretching back from the entrance back to the main road.
Last year, reports suggested the hospital was badly damaged.
The charity MSF said in March 2021 that its teams had found health facilities across the region - including Maiani hospital - "looted, vandalised and destroyed in a deliberate and widespread attack".
Of 106 centres they visited, only 13% were working normally. MSF said, "While some looting may have been opportunistic, health facilities in most areas appear to have been deliberately vandalised to make them non-functional."
The BBC has spoken to a senior aid worker in the neighbouring town of Shire 95 kms (59 miles) to the east of Shiraro. He says about 210,000 people have fled Shiraro and the surrounding areas to Shire since 1 September.
"For one week before the people left the town, there was continuous shelling, it was 24 hours, continuous," he told the BBC.
We have hidden the aid worker's identity for his safety.
He told the BBC that according to those fleeing and his staff who had been posted to Shiraro, Maiani Hospital is now in the hands of Eritrean and Ethiopian government forces.
On 13 September, before the latest satellite images were taken, the head of the Tigrayan Forces, General Tedesse Werede, told local media that "the joint Eritrean and Ethiopian army in Shiraro have taken control of areas from Shiraro to Ademeiti".
It is not clear who is currently in charge of Shiraro - the aid worker in Shire told the BBC reports change day by day.
Less than a kilometre south of the hospital lies what Maxar, the company which released the images, identifies as "towed artillery in firing positions" - they are seen dotted in an uneven line through the middle of this picture.
