Israel-Gaza live updates: 3 premature babies die at Al-Shifa Hospital, doctor says

About 72,000 people have fled northern Gaza in the last four days, moving south along a corridor opened by Israeli military forces, the United Nations said Thursday.

About 50,000 traveled along Salah al-Din Road in the hours the corridor was opened on Wednesday, the U.N. Office for the Coordination of Humanitarian Affairs said.

“Clashes and shelling on and around the road reportedly continued, endangering evacuees with reports of corpses alongside the road,” the U.N. statement said.

Many have arrived at the corridor on foot. Some who’ve driven there have been told to leave their vehicles along the outskirts of Gaza City, the U.N. said. Videos and photos released by the Israel Defense Forces have shown crowds marching while waving white flags.

“The evacuees then walk 4-5 kilometres down the corridor, with an estimated distance of up to 20 kilometres for those traveling farthest,” the U.N. said.

Israel is considering a proposal presented by Egypt and Qatar for a humanitarian pause in exchange for the release of hostages, sources tell ABC News.

The U.S. is in close coordination with all parties negotiating this possible deal, the sources said and no final deal has been reached yet.

No further details were available.

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.
