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."

Through tears and voices choked with raw emotion, people whose family members are believed to held hostage by Hamas pleaded for help during a Republican-led press conference at the U.S. Capitol on Tuesday.

Doris Liber told reporters that her son, Guy Iluz, called her as Hamas unleashed its terrorist attack against Israel on Oct. 7 and she hasn't heard from him since.

"I'm here because it's been 30 days. Every day is like eternity to me," Liber, who holds joint Israeli-American citizenship, said. "We don't have a list of the hostages. We don't know their condition. I don't have anything. So I need your help."

She described the last time she spoke to her son.

"We hear shots in the background," she said. "He was shot in the arm and he wasn't able to stop the bleeding and he was trying to say his last words."

“I tried to, you know, tell him, ‘Guy I love you. Don't worry, nothing's going to happen. I'm going to end the call now. I'm going to send somebody now to get you,'" she continued. "And that's what I did. I hung up and I regret that since I didn't hear from him since."

Yonatan Lulu-Shamriz said he was awoken by his pregnant wife as the sirens began to sound in their kibbutz. They grabbed their 3-year-old daughter, huddled in a safe room and listened as their neighbors were slaughtered, he said. Soon his brother, Alon, called to report he was under attack, Lulu-Shamriz said.

“We don't know what is their condition," Lulu-Shamriz said. "This is a wake-up call not only for Israel, not only for the Jewish community. This is a wake-up call for all of you -- all of you here, all of America, all of Europe. You are next. You are next. And we should do everything that we can to stop these atrocities."

House Speaker Mike Johnson vowed to "take action."

"We're resolved to help," the newly minted speaker said. "House Republicans want to do that."
