For three weeks, Israel has been bombing the Gaza Strip as part of its war with Hamas.
The two sides have published conflicting accounts of the toll taken by the airstrikes. Satellite data gives us an independent view.
Every 12 days, NASA’s Sentinel-1 satellite passes three times over the Gaza Strip, firing out radar waves and listening for their echo. Buildings typically bounce the signals right back, but rubble scatters them in all directions.
By comparing signals before the war with those taken more recently, we can estimate the scope and scale of the destruction.

By 13 October, six days after Hamas launched its attacks in southern Israel, much of Gaza City had been hit by airstrikes.
The satellite data suggests 15% of buildings in northern Gaza were damaged or destroyed in less than a week, along with 2% in southern Gaza.
That same day, Israel ordered all 1.1 million residents of northern Gaza to flee southwards to relative safety.
Since then, however, Israel has stepped up its bombing of the south.
The map below shows the estimated damage to buildings across Gaza on 13 and 25 October, with the most damaged areas highlighted in yellow.
Almost half of all new damage detected between 14 and 25 October was in southern Gaza (47%), up from 14% before the evacuation order.
While there was a decrease in new damage across the Gaza Strip during those two weeks, the level of destruction in southern Gaza increased by 85%.
A spokesperson for the Israeli Defence Forces declined to comment.
Many of those who fled the north after 13 October have ended up in the Gaza Strip’s second most populous city, Khan Younis.
Since then, satellite data shows neighbourhoods across the city have sustained damage.
The video below, uploaded to Snapchat on 24 October, shows smoke rising from behind a school in Khan Younis.
Sky News has verified the location of the footage, and satellite analysis shows that a row of buildings immediately behind the school sustained damage between 14 and 25 October.
The Gaza Strip has been under aerial bombardment since Hamas’s 7 October attack, in which the Israeli government says more than 1,400 were killed.
Israel says that Hamas is still holding more than 200 people hostage inside the enclave. Five British citizens remain missing.
The airstrikes come as Israel prepares to launch an anticipated ground invasion of the Gaza Strip.
According to Gaza’s health ministry, which is controlled by Hamas, more than 6,500 people have been killed in the airstrikes – two-thirds of them women and children.
Sky’s satellite data suggests that one in four buildings in northern Gaza (25%) have been damaged or destroyed in the past three weeks, along with 8% of those in the south.
The Rimal neighbourhood of Gaza City has been hit particularly hard.
This video below, uploaded to Snapchat on 20 October and verified by Sky News, shows the local high street in ruins.
From the satellite analysis, we can see that the video shows just a small part of the destruction in Rimal.

Sky’s analysis of satellite data followed a method developed by academics and promoted by NASA.
This is a conservative estimate – Sky News has only classified an area as damaged if the satellite records at least a 30% decrease in surface smoothness over a 1,600 square metre area.
Damage to a single building, or even its total destruction, is unlikely to reach that threshold. Damage to the side of buildings may not be detected at all.
The Gaza Ministry of Public Works says that 27,781 housing units, or around 7% of the total, have been destroyed or rendered uninhabitable since 7 October.

The biggest city in the Sahel has been ransacked and left in ruins.
War erupted in Sudan’s capital Khartoum in April 2023 and sent millions searching for safety.
The city was quickly captured by the paramilitary Rapid Support Forces (RSF) after a power struggle with the Sudanese Armed Forces (SAF) for total control.
At least 61,000 people were killed from the fighting and siege conditions in Khartoum state alone.
Thousands more were maimed and many remain missing.
The empty streets they left behind are lined with charred, bullet-ridden buildings and robbed store fronts.

A shell of a home
I have to strain my eyes to see the turn to my house. All the usual markers are gone. There are no gatherings of young people drinking coffee with tea ladies in the leafy shade – just gaping billboard frames that once held up advertisements behind cars of courting couples parked by the Nile.
Our garden is both overgrown and dried to death.

Everyone in Khartoum is coming back to a game of Russian roulette. Searching out their houses to confirm suspicions of whether it was blasted, burned or punctured with bullets.
Many homes were looted and bruised by nearby combat but some are still standing. Others have been completely destroyed.

The outside of our house looks smooth from the street but has a crack in the base of the front wall visible from up close.
It is likely a bomb fell nearby and shook the house at its base – a reminder of the airstrikes and shelling that my parents and their neighbours fled.
Inside, the damage is choking.
Most of the furniture has been taken except a few lone couches.
The carpets and curtains have been stripped. The electrical panels and wiring pulled out. The appliances, dishes, glasses and spices snatched from the kitchens.

The walls are bare apart from the few items they decided to spare. Ceilings have been punctured and cushions torn open in their hunt for hidden gold.
The walls are marked with the names of RSF troops that came in and out of this house like it was their own.
The home that has been the centre of our life in Sudan is a shell.

A paramedic in Gaza who was detained for more than five weeks following an Israeli attack that killed 15 aid workers has been released, the Palestinian Red Crescent Society (PRCS) said.
Asaad al Nsasrah was one of 17 aid workers who were attacked in Tel al Sultan in southern Gaza by Israeli forces on 23 March.
Asaad was one of two first responders who survived – the other 15 were killed.
He was initially thought to be missing, as his body was not among the dead. It was not until 13 April, three weeks after the attack, that Israel confirmed Asaad was alive and in Israeli detention.
The PRCS announced Asaad’s release on X and shared a video of him reuniting with colleagues.

How two hours of terror unfolded
The PRCS claimed the Israeli military’s investigation was “full of lies”.
Asaad’s voice can be heard in a video, initially published by the New York Times, that shows the moments leading up to the attack on the aid workers.
The video was discovered on Rifaat Radwaan’s phone, which was found on his body by rescue workers five days after the attack.
Among those killed were one UN worker, eight paramedics from the PRCS and six first responders from Civil Defence – the official fire and rescue service of Gaza’s Hamas-led government.

Mark Carney’s Liberal Party has won the election in Canada, according to Canadian broadcasters, but it is too soon to say whether they will form a majority government.
Mr Carney, who took over as prime minister after Justin Trudeau stepped down earlier this year, has beaten the leader of the Conservative Party Pierre Poilievre, according to CBC and CTV News projections.
However, it is too soon to say whether the Liberals will form a majority government, they added. The party has not yet secured the 172 electoral districts it needs for a majority.

The election initially appeared to be a clear-cut race for the opposition Conservatives, who were enjoying a double-digit lead over the Liberals before Mr Trudeau resigned, and an intervention by Donald Trump led to a surge in support for Mr Carney’s party.
Mr Trump has repeatedly called for Canada to become the 51st US state since he was elected president for a second time and has imposed sweeping tariffs on Canada.

Trump on why he wants Canada to be 51st state
Mr Carney has vowed to take a tougher approach with Washington over its tariffs and has said Canada will need to spend billions to reduce its reliance on the US.

If Mr Carney’s party only captures a minority of the House’s 343 seats, he will be forced to negotiate with other parties in order to stay in power.
Such minority governments rarely last longer than two-and-a-half years in Canada.
Canadians went to the polls after 11 people were killed in a deadly attack at a Vancouver street fair over the weekend that led to the suspension of campaigning for several hours.
Police have ruled out terrorism and said the suspect is a local man with a history of mental health issues.
