The Israeli military said in a statement Wednesday that forces were operating in Gaza City, as well as in northern Gaza.
It said without elaborating that in Jabaliya, an area hard-hit in multiple rounds of fighting, an air strike killed “a number of” Hamas fighters.
Troops struck roughly 120 targets throughout Gaza over the past day, including militant cells, tunnels and booby-trapped structures, among others, the military said.
Overnight strikes kill at least 21
One Israeli strike hit a house Tuesday in the northwestern side of Gaza City, killing at least 12 people, according to the Shifa Hospital, which received the casualties.
The dead included six children and two women, according to the Health Ministry's casualty list.
Another strike hit an apartment in the Tal al-Hawa area in northern Gaza, killing at least six people. Among the dead were three children and two women, including one who was pregnant. Eight others were wounded, the ministry said.
A third strike hit a tent in the Naser neighborhood in Gaza City late Tuesday and killed three children, Shifa Hospital said.
The Israeli military did not immediately respond to a request for comment on the strikes. It blames Hamas for civilian casualties because the fighters operate from populated areas.
