“People have set up fires inside collapsed buildings as a way to warm themselves during these difficult weather conditions in northern Gaza,” Al Jazeera’s Hani Mahmoud reports from Gaza City.

“There is a lack of aid, tents and better protection for people here. They are staying in severely damaged buildings due to a lack of shelters in these areas.”

There have been three documented cases of people dying under similar buildings that were collapsed in recent days, he said.
