Researchers mapped the damage in Gaza, and more than a third of the buildings have been wrecked as the war moves south

• Israel's campaign in Gaza started in the north but has now shifted to the southern area.
• Researchers mapping the damage say more than a third of the buildings in the strip have been destroyed.
• Tens of thousands of munitions — a mix of precision and unguided — have been dropped on the enclave.

Israel's continued bombardment of the Gaza Strip in response to the Oct. 7 Hamas terror attacks has damaged more than a third of all buildings that existed there before the war began over two months ago, according to analysis by a pair of satellite data researchers.
