Nearly 100,000 Gaza buildings may be damaged, satellite images show
New satellite images commissioned by the BBC reveal the extent of destruction across northern Gaza, before the start of the temporary ceasefire between Israel and Hamas.
The satellite images were taken last Thursday, just before the suspension of hostilities came into force, following weeks of Israeli air strikes and on-the-ground fighting. Separate satellite data analysis also provides a snapshot of the destruction across the whole of Gaza.
Drone footage and verified video also show buildings and entire neighbourhoods reduced to rubble. While northern Gaza has been the focus of the Israeli ground offensive and has borne the brunt of the destruction, widespread damage extends across the entire strip.
Israel says northern Gaza, which includes the major urban centre of Gaza City, was a "centre of gravity of Hamas", the group behind the deadly 7 October attacks on Israel. Israel says its bombing campaign has successfully targeted Hamas commanders and fighters and accuses the group of embedding itself in civilian areas.
Satellite data analysis suggests that almost 98,000 buildings across the whole Gaza Strip may have suffered damage, with most of it concentrated in the north - as shown in the above map.
Analysis of the data was carried out by Corey Scher of City University of New York Graduate Center and Jamon Van Den Hoek of Oregon State University. It is based on comparisons of two separate images, revealing changes in the height or structure of buildings which suggests damage.
We have analysed satellite imagery from several areas with extensive damage.
North-eastern areas hit by first air strikes
The cities of Beit Lahia and Beit Hanoun in the north and north-east of the Gaza Strip were among the first to be targeted by air strikes after the 7 October attacks by Hamas. The Israel Defense Forces (IDF) said the area was a hideout for Hamas.
Parts of Beit Lahia, which overlooked olive groves and sand dunes stretching towards the border with Israel, have been flattened. The satellite image below shows an area in the north-east of Beit Lahia, where a significant block of buildings has now been destroyed.
Bulldozers appear to have cleared roads through the rubble and the Israeli military has cleared land and set up defensive positions in surrounding fields.
The IDF also struck the small nearby city of Beit Hanoun, less than 1.6km (1 mile) from the border. It said 120 targets were hit in the area on the first day of air strikes.

As the images above show, a skyline of multi-storey buildings and a mosque has gradually been reduced to rubble between 14 October and 22 November.
Five-star hotel damaged, nearby neighbourhood flattened
After weeks of air strikes on Gaza, Israel moved in on the ground - tanks and bulldozers going through areas which had been heavily bombarded. The IDF worked its way southwards along the coast towards Shati (Beach) refugee camp, in the Gaza City area.
As the image below shows, a whole series of craters are visible in what was once a residential area. Some of the buildings on the beach front, which boasted Gaza's first five-star hotel, the Al-Mashtal, as well as huts and restaurants, appear to have been partially destroyed.
About a week after the air strikes began, the IDF warned Palestinians in northern Gaza to move south of a river known as Wadi Gaza for their own safety.
Despite the warning and hundreds of thousands of people fleeing Gaza City, areas in the south have continued to be targeted.
Camp buildings destroyed
Nuseirat refugee camp in central Gaza was hit several times before the temporary pause in hostilities began. The camp was said to be home to about 85,000 people, according to the UN.

In this verified video, which has emerged online in the past few days, people are seen picking through the rubble of collapsed and damaged buildings.
The distinctive black chimney stacks of the Gaza Power Plant, situated just north of the camp, are visible in the background.
The BBC has approached the IDF for comment.
Damage and Israeli orders push a million people to southern Gaza city
In Khan Younis, in southern Gaza, thousands of people are living in tents or the rubble of bombed-out buildings.
Although the damage is not as widespread as in the north, up to 15% of buildings across the city may have been damaged, according to Corey Scher and Jamon Van Den Hoek's analysis.
The break in the air strikes created by the truce has encouraged some people to venture out to markets. In the picture below damaged buildings can be seen near the city's Grand Mosque.
As well as pushing down from the north, Israeli forces also cut across the Gaza Strip westwards, isolating Gaza City from the south.
In this image below, taken to the south of Gaza City, we can see what was previously a populated residential area, cleared by the IDF with heavy machinery and a road bulldozed towards the western Mediterranean shoreline.
You can also see dozens of military vehicles, including tanks, grouped behind fortifications made from earth.
