The Palestine Red Crescent Society said it received 106 trucks loaded with aid, including food, water and medical supplies, from the Egyptian Red Crescent, Wednesday.

The trucks arrived via the Rafah crossing, PRCS said in a statement.

The group also said it received five ambulance vehicles from Kuwait.

The United Nations Relief and Works Agency for Palestine Refugees in the Near East and World Health Organization announced Wednesday that medical supplies and medicines have been delivered to Al-Shifa Hospital in Gaza.

This is the second delivery to the hospital since the attacks on Gaza began, the two organizations said in a joint statement.

"While welcome, the quantities we delivered are far from sufficient to respond to the immense needs in the Gaza Strip. The medical conditions at Al-Shifa - the largest hospital in the Gaza Strip and one of the oldest Palestinian health institutions - are disastrous." the UNRWA and WHO said.

The organizations said there are currently "almost two patients for every bed available."

"The emergency department and wards are overflowing requiring doctors and medical workers to treat wounded and sick patients in the corridors, on the floor and outdoors," NRWA and WHO said.

The issue of hostages remains a priority for Hamas in its conflict with Israel, the spokesperson of the group's armed wing, al-Qassam Brigades, said Wednesday.

"The only clear path to this issue is a comprehensive or partial prisoner exchange deal," Abu Obeida said in a video statement on Telegram.

He said Hamas has its own civilians and fighters in Israeli prisons, and Israel has the same types of groups in Hamas’ group’s custody.

"There is absolutely no solution to this issue other than this path and a swap category by category or as a comprehensive process," he said.

Obeida accused Israel of "hindering and destroying all efforts to hand over foreign hostages" by refusing to create the right conditions to do so and jeopardizing captives' lives.

The group's fighters have completely or partially destroyed 136 Israeli military vehicles since the start of the ground invasion as they clashed with Israeli forces in northwest and southern Gaza City and the northern part of the Gaza Strip, he said.

Israeli Prime Minister Benjamin Netanyahu said Wednesday evening that "there will be no cease-fire without the release of our hostages -- everything else is false."

During brief remarks in New Delhi Friday morning, U.S. Secretary of State Antony Blinken swiftly acknowledged the Biden administration’s “appreciation” of Israel’s commitment to four-hour pauses with three-hour notice in specific areas and corridors of Gaza “that will allow people to move more safely, freely to get out of harm's way and also to access assistance.”

“At the same time, much more needs to be done to protect civilians and to make sure that humanitarian assistance reaches them," he continued. "Far too many Palestinians have been killed. Far too many have suffered these past weeks, and we want to do everything possible to prevent harm to them, and to maximize the assistance that gets to them.”

The secretary said they have established basic principles to guide the effort for lasting peace and security in the region: no use of Gaza as a platform for launching attacks against Israel, no diminution in the territory of Gaza and a commitment to Palestinian-led governance.

Blinken reaffirmed that the administration had “long been committed” to a two-state solution, and the terror attacks of Oct. 7, he said, only redouble American commitment to the peace process.

“But now we've had the events of October 7 -- the almost, beyond the human imagination -- horror of October 7. And I think that only reinforces us in our conviction and our commitment to durable and lasting peace which again, we see through two states,” he said.

On humanitarian assistance, Blinken said that “more than plans, we have a concrete way forward,” including ensuring that there are adequate supplies of fuel for the trucks coming in and that hospitals and desalination plants “have what they need.”

“It's always a process and moving from an understanding, moving from an agreement to implementation is what we're working on right now,” he said.
