The U.S. needs to keep troops deployed in Syria to prevent the Islamic State group from reconstituting as a major threat following the ouster of Bashar Assad's government, Defense Secretary Lloyd Austin told The Associated Press.

American forces are still needed there, particularly to ensure the security of detention camps holding tens of thousands of former IS fighters and family members, Austin said Wednesday in one of his final interviews before he leaves office.

Israeli soldiers recovered the body of a 53-year-old hostage in an underground tunnel in southern Gaza, the military said Wednesday, and the army was determining if another set of remains belongs to the man's son.

The discovery of Youssef AlZayadni's body comes as Israel and Hamas are considering a ceasefire deal that would free the remaining hostages and halt the fighting in Gaza. Israel says about a third of the remaining 100 hostages have died, but believes as many as half could be dead.

The U.S. military says it carried out Wednesday a wave of strikes against underground arms facilities of Yemen’s Iran-backed Houthi rebels.

Israeli airstrikes in southern Gaza killed at least 17 people late Tuesday, nearly all of them women or children, the territory’s Health Ministry said.

Five kids were killed in the same tent as they sheltered together in a camp for displaced Palestinians in Muwasi, said Ahmed al-Farra, director of the child ward at Nasser Hospital in nearby Khan Younis. Their bodies were among the eight children and five women brought to the hospital.

Talks aimed at cementing a truce in Gaza between Israel and Hamas are ongoing, with "technical meetings" taking place between the parties, mediator Qatar's foreign ministry said Tuesday.

The Israeli military launched a wave of raids across the occupied West Bank overnight and into Tuesday, killing at least three Palestinians it said were militants a day after a deadly shooting attack.

Two rebel groups from Syria's Druze minority said on Monday they were ready to join a national army after Islamist-led opposition fighters toppled president Bashar al-Assad last month.

The new Syrian authorities face the mammoth challenge of rebuilding state institutions shaped by the Assad family's repressive five-decade rule, including the army and security apparatuses that have all but collapsed.

The U.S. has eased some restrictions on Syria's transitional government to allow the entry of humanitarian aid after Islamist insurgents ousted Syrian leader Bashar Assad last month.
