Israel says it's launched a significant attack in the north of Gaza – there were reports on Sunday night of huge explosions and intense airstrikes. The country's military has said this:

• IDF forces have "surrounded" Gaza City
• Troops have reached the coastline, effectively dividing the Strip into "Gaza North and Gaza South"
• Israel is still "allowing a corridor" for the residents of the northern Gaza Strip and Gaza City to go south
• Israel "will continue to attack strongly and continue to intensify our ground operation in the northern Gaza Strip and greater Gaza City"

The Hamas-run health ministry says almost 10,000 people have been killed in Gaza since Israel started its campaign there, in response to the Hamas attacks of 7 October.
