At least 23 people were killed, including a family of 10, in Israeli strikes on the Gaza Strip overnight, the Associated Press reported, citing local health authorities.
Israel has suspended a truce with the Palestinian organization "Hamas" last month and renewed the bombing, killing hundreds of people and seizing large swaths of territory.
A strike in the southern city of Khan Younis overnight killed five children, four women and a man from one family, Nasser Hospital, where the bodies were taken, said.
A further 13 people, including nine children, were killed in strikes in the northern Gaza Strip.
The Israeli army said it was trying to avoid civilian casualties and blamed Hamas, which it said was operating in residential areas, for the deaths.
Meanwhile, the UN Office for Humanitarian Affairs said almost all of the enclave's more than two million residents now rely on just one million meals prepared daily in aid agency kitchens.
Other food distribution programmes have been shut down due to a lack of supplies, and the UN and other aid agencies are sending their remaining supplies to soup kitchens.
The only other way to get food in the Gaza Strip is through markets, the AP noted. But most people cannot afford to buy food because of soaring prices and widespread shortages that mean that for about 80 percent of the population, humanitarian aid is their main source of food, the UN World Food Programme said earlier this month.
Water is also becoming increasingly scarce, with Palestinians lining up in long lines to fill their containers from trucks, the AP noted.
Yesterday, Israeli Defense Minister Israel Katz ruled out any possibility of resuming humanitarian aid deliveries to the enclave after accusing "Hamas" of diverting aid to maintain its rule.
