Why are Hamas tunnels under Gaza City a key battlefield for Israel?   The tunnels under Gaza are a prime objective for Israel as it expands a ground offensive into Gaza from the north to hit Hamas in retaliation for the Islamist group’s deadly surprise attack into southern Israel on Oct. 7.   Health authorities in Hamas-run Gaza say that 8,525 people, including 3,542 children, have been killed in Israeli attacks since Oct. 7. About 1,400 people, mainly civilians, were killed in the cross-border Hamas assault on Oct. 7, Israel says.   Reuters has been unable to independently verify casualty counts.   🔗 Read about Israel’s latest incursion in Gaza City at our link in bio.   #Reuters #video #videonews #topstories #topnews #Israel #Israelis #Hamas #Palestinians #Palestinianterritories #Palestinian #Hamasattack #conflict #Gaza #IsraelHamas #IsraelHamaswar #IsraelHamasconflict  #GazaCity #refugee #refugeecamp #Hamastunnels
