Munir al-Barsh, the general director of the ministry, which operates under Hamas authority, told AFP that 11 people were killed and 20 more were wounded "as a result of strikes carried out by the occupation targeting civilians in a tent and an apartment".

Barsh said the wounded arrived at hospitals in Gaza City in the north and Khan Yunis in the south.

Israel "continues its serious violations of the ceasefire agreement amid a severe shortage of medical supplies, medicines and medical equipment", Barsh added.

A US-brokered ceasefire in place since October progressed into its second phase in January, which is supposed to include Hamas's disarmament, a gradual Israeli withdrawal and the deployment of an international stabilisation force.

Israel and Hamas have repeatedly accused each other of violating the truce.

Gaza's Hamas-run government press office said Saturday that the strike on the tent in the south killed seven members of one displaced family, including a child and an elderly person.

According to the health ministry, 509 people have been killed since the ceasefire took effect on October 10.

Almost all of Gaza's population has been displaced at least once during the war in the tiny coastal territory, and hundreds of thousands still live in tents or makeshift shelters.

The war was sparked by Hamas's October 7, 2023 attack on Israel, which resulted in the deaths of 1,221 people, according to an AFP tally based on official Israeli figures.

The Israeli retaliation flattened much of Gaza, which was already suffering from previous rounds of fighting and from an Israeli blockade imposed since 2007.

The two-year war has left more than 71,769 people dead in Gaza, according to the health ministry, whose figures are considered reliable by the United Nations.
