An Israeli airstrike Monday in a Damascus neighborhood killed a high-ranking Iranian general, Iranian state media said.

The killing of Seyed Razi Mousavi, a long-time adviser of the Iranian paramilitary Revolutionary Guard in Syria, comes as clashes along the Lebanon-Israel border between Hezbollah and Israel continue to intensify with fears of the Israel-Hamas war sparking a regional spillover with Iran-backed groups. The Israeli strikes killed two other generals earlier this month in Syria.

Israel struck the Sayida Zeinab neighborhood, located near a Shiite Muslim shrine, Iran’s official news agency IRNA and Britain-based opposition war monitor the Syrian Observatory for Human Rights said. IRNA described Mousavi as a close companion of Gen. Qassim Soleimani, the head of Iran’s elite Quds Force who was slain in a U.S. drone strike in Iraq in January 2020.

Neither the Israeli military nor Syrian state media immediately issued a statement about the attack.

Though IRNA didn't provide other details about the attack, the Syrian Observatory for Human Rights said the Israeli military targeted Mousavi after he entered a farm in the area, which allegedly was one of several offices for Hezbollah. The Lebanese militant group, alongside Iran and Russia, has played a key military role in keeping President Bashar Assad's government in power throughout the Syrian conflict.

Israel has carried out hundreds of strikes on targets inside government-controlled parts of war-torn Syria in recent years.

It doesn't usually acknowledge its airstrikes on Syria. But when it does, it says it's targeting Iranian-backed groups there that have backed Assad's government.

Hamas, Islamic Jihad reject Egypt's proposal for cease-fire, hostage release: Egyptian security source

Hamas and the Islamic Jihad have rejected an Egyptian proposal that they relinquish power in the Gaza Strip in return for a permanent cease-fire, an Egyptian security source confirmed to ABC News.

Egypt proposed a "vision,” also backed by Qatari mediators, that would involve a cease-fire in exchange for the release of more hostages and lead to a broader agreement involving a permanent cease-fire, along with an overhaul of leadership in Gaza, the Egyptian security source said. However, Hamas and the Islamic Jihad rejected the proposal, the source said.

The Israeli War Cabinet was planning on meeting to discuss this proposal Monday evening local time. It is unclear if they will still discuss the proposal.

At least 68 killed in Israeli airstrike on Gaza refugee camp, health ministry says

At least 68 people were killed by an Israeli airstrike on a refugee camp in the Gaza Strip on Sunday night, according to Gaza's Hamas-run Ministry of Health.

The strike hit the Al-Maghazi refugee camp in central Gaza, east of Deir al-Balah. At least 12 women and seven children were among the dead, according to The Associated Press, which cited early hospital figures.

When asked for comment, the Israel Defense Forces told ABC News on Monday: "The IDF received reports of an incident in the Maghazi camp and is reviewing the incident. Despite the challenges posed by Hamas terrorists operating within civilian areas in Gaza, the IDF is committed to international law including taking feasible steps to minimize harm to civilians."

Biden says he did not ask for cease-fire on call with Netanyahu

President Joe Biden said he did not ask for a cease-fire during a call earlier Saturday with Israeli Prime Minister Benjamin Netanyahu.

"I had a long talk with Netanyahu today. It was a private conversation," he told reporters while leaving the White House for Christmas at Camp David.

He later said, "I did not ask for a cease-fire."

The leaders discussed Israel's military operation in Gaza, the humanitarian crisis in Gaza and securing the release of the remaining hostages, according to a readout of the call released by the White House. The two agreed to remain in "regular consultation," the readout stated.

Biden also did not respond to questions about a new Wall Street Journal report that in the days after the Oct. 7 attack he convinced Netanyahu against a preemptive strike on Hezbollah forces in Lebanon.

ABC News has not confirmed the report.

US hostage confirmed dead

Gadi Hagi, a 73-year-old American-Israeli hostage and member of Kibbutz Nir Oz, has been confirmed dead, the kibbutz said.

Hagi was killed on Oct. 7 at the kibbutz and his body was taken to Gaza where it's still being held, according to a kibbutz spokesperson.

Hagi’s wife, 70-year-old Judy Weinstein, is wounded and still being held hostage, the kibbutz said.

Hagi and his wife were shot and kidnapped on Oct. 7, according to the Hostage Center.

"Gadi was a man full of humor who knew how to make those around him laugh," the Hostage Center said in a statement. "A musician at heart, a gifted flautist, he played in the IDF Orchestra and was involved with music his whole life."

Hagi was a father of four and a grandfather of seven.

Hagi reportedly has ties to New York.

"May Gadi's memory be a blessing," New York Gov. Kathy Hochul wrote on social media. "There are still many hostages -- including many with New York connections -- being held in Hamas captivity."

President Joe Biden said he was "heartbroken by the news."

"We continue to pray for the well-being and safe return of his wife, Judy," Biden said in a statement. "We are praying for their four children, seven grandchildren, and other loved ones and are grieving this tragic news with them."

Biden said Hagi's daughter joined, via phone, his meeting last week with families of hostages.

"Those families bravely shared with me the harrowing ordeal that they have endured over the past months as they await news of their loved ones," Biden said. "I reaffirm the pledge we have made to all the families of those still held hostage: we will not stop working to bring them home."
