He added the amount was "only a drop in the ocean".

The blood and plasma were delivered to Nasser Medical Complex for onward distribution to hospitals "facing critical shortages amid a growing influx of injuries, many linked to incidents at food distribution sites", he said.

Before Thursday's strike at the market, at least 14 Palestinians had been killed and dozens injured in Israeli military attacks across Gaza since midnight, a spokesperson for the Hamas-run Civil Defence said.

Rescue teams evacuated 14 bodies, including those of three Palestinians who were waiting for humanitarian aid near the Wadi Gaza bridge close to the Netzarim corridor in central Gaza.

A medical source at Al-Awda Hospital nearby confirmed that three Palestinians were killed and several others injured by Israeli gunfire near the Wadi Gaza bridge.

Witnesses said Israeli drones opened fire at a big crowd of civilians reportedly waiting for humanitarian aid at the time of the attack.

The Israel Defense Forces (IDF) told the BBC that overnight, a gathering was identified in an area adjacent to troops in the Netzarim corridor, and troops fired warning shots to prevent suspects from approaching them.

The IDF said it was aware of reports regarding the number of injured individuals in the area, but said an initial inquiry suggested the number does not align with the IDF's information. However, the details of the incident are under additional review, the IDF added.

Elsewhere, five people were killed in an Israeli air strike on a school sheltering displaced families in western Gaza City.

In the Al-Mawasi area of Khan Younis, in the south of the Strip, five members of the Abu Arab family were killed when an Israeli air strike hit a tent sheltering displaced persons. Another Palestinian was also killed in a strike that hit a tent in Al-Mawasi.

Others were wounded in the strikes.

The IDF said it was looking into these reports, but requested specific coordinates and times. In general, the IDF said it was "operating to dismantle Hamas military capabilities".

The Israeli military launched a campaign in Gaza in response to Hamas's 7 October 2023 attack on Israel, in which about 1,200 people were killed and 251 others were taken hostage.

At least 56,259 people have been killed in Gaza since then, according to the territory's Hamas-run health ministry.
