UN report based on AI says early war damage in Beirut and Mount Lebanon reached $365 million by April
A UN-backed AI assessment pegs early war damage in Beirut and Mount Lebanon at $365 million through April, but says the total is incomplete.
Intelligence analysis by GPT-5.4 Mini
Using satellite imagery and field checks, a UNDP-led report estimates direct damage in Beirut and Mount Lebanon at $365 million through mid-April. Most losses were in Mount Lebanon, and the authors say the real bill is likely higher.
A group used satellite pictures and on-the-ground checks to count broken buildings and damaged homes in part of Lebanon. It is like trying to count smashed windows from far away with binoculars, but the whole house is still being torn up, so the final number is not ready yet.
Analysis
What the report found
A joint assessment by UNDP, Lebanon's CNRS-L, the Lebanese Army, and the UN Department of Safety and Security estimated direct war damage in Beirut and Mount Lebanon at about $365 million as of mid-April 2026. The report used GeoAI, satellite imagery, and field verification conducted between February and April.
It counted 146 buildings fully destroyed, 264 buildings partially damaged, and direct damage to 54 residential apartments. It also estimated rubble at 648,942 cubic meters.
Where the damage was concentrated
Mount Lebanon bore the bulk of the losses, with $349.6 million in damage, compared with $15.4 million in Beirut. Within the governorates, Baabda was the hardest hit area, with 133 destroyed buildings and 243 partially damaged buildings. The most affected localities included Haret Hreik, Chiyah, Burj al-Barajneh, Laylaki, Shoueifat, Amrousieh, Mazraa, Basta, Ain al-Mreisseh, and المصيطبة.
Why the number is still provisional
The article stresses that the figure is not the final cost. Satellite analysis cannot see inside buildings, so some apartment-level damage may be missed. Ongoing Israeli demolition and clearing operations also mean the damage count changes daily.
The report's scope is limited to Beirut and Mount Lebanon, while earlier government estimates covered all regions, including the south. That is why the article argues the national total is likely much larger than the UN assessment.
Bigger picture
The paper says the damage is already far above what can be treated as a local repair bill. The article argues the final cost could exceed the World Bank's estimate of Lebanon's 2024 war losses, put at $14 billion, and may move beyond $20 billion if the destruction continues.
Key points
- A UNDP-led assessment puts direct damage in Beirut and Mount Lebanon at $365 million through mid-April 2026.
- The report used GeoAI, satellite imagery, and field verification, but says the estimate is still incomplete.
- Baabda was the hardest-hit area, while damage was concentrated in Beirut's southern suburbs and parts of the capital.
- The article says the final cost is likely to rise as more field checks are completed and demolition continues.
If the field checks continue, the estimate can become more accurate and help direct rebuilding efforts where the damage is heaviest. The report's mix of satellite data and ground verification could also give officials a clearer base for future recovery planning.
Because satellite images cannot see inside buildings, the real damage may be higher than the report's first estimate. The article also says ongoing demolition and clearing work means the numbers keep changing, which could push the final bill well above the current figure.
