Israel-Gaza updates: Israel says it agrees to cease-fire, hostage release

At least one person was killed and several others were injured Thursday in a shooting on a main road just outside Jerusalem in the Israeli-occupied West Bank, according to Israeli authorities.

Highway 1 was packed with cars when gunfire erupted Thursday morning near a checkpoint between Jerusalem and the Israeli settlement of Ma'ale Adumim. Three "terrorists" armed with automatic weapons pulled up in a vehicle, got out and opened fire at cars that were standing still in the traffic jam, according to the Israel Police.

Israeli security forces who were already on scene "neutralized" two of the suspects, police said. A third suspect who had tried to escape was later found and also "neutralized," according to police.

Medics arrived and "ran from vehicle to vehicle" searching for victims, according to Israel's rescue service MDA. A man in his 20s was pronounced dead at the scene while several others were transported to area hospitals, including four people who were moderately injured with gunshot wounds, MDA said.

Israeli Minister Benny Gantz on Wednesday expressed cautious optimism that a new outline for a possible hostage deal could move forward.

Gantz, a member of the Israeli war cabinet, said at Israel's Defense Headquarters Wednesday that there are "attempts" to "promote a new outline" for a hostage deal, and there are "initial signs that indicate the possibility of moving forward."

"We will not stop looking for the way, and we will not miss any opportunity to bring the girls and boys home," Gantz said.

Eight patients who died because of a lack of electricity at Nasser Medical Complex in Gaza are still in their beds inside of the hospital among living patients, the Hamas-run Gaza Ministry of Health said Wednesday.

The Ministry of Health said the bodies are still in the hospital because Israeli forces refuse to remove them.

The bodies "have begun to swell and show signs of decomposition, posing a danger to other patients," the Ministry of Health said in a statement.

Israeli authorities denied these claims and said no bodies are still inside Nasser Hospital.

The Israel Defense Forces has been operating inside of Nasser Hospital for the last week. On Monday, the IDF announced its soldiers had arrested 200 suspected Hamas members at Nasser Hospital.
