The Gaza war raged on into a fourth month on Sunday as the Israeli army pounded the Palestinian territory with strikes and US top diplomat Antony Blinken was back in the Middle East seeking to avoid a wider escalation.

Israeli bombardments had killed at least 113 people in the past 24 hours, said the health ministry in the besieged territory run by Islamist militant group Hamas, with two journalists among the victims when their car was struck in Rafah.

The journalists killed, who were working for Al Jazeera, were identified as Mustafa Thuria, a video stringer who also worked for AFP and other media, and Hamza Wael Dahdouh, the son of the Qatari network's Gaza bureau chief who earlier lost his wife and two other children in an Israeli strike.

"Hamza was everything for me," Dahdouh said on Al Jazeera television, adding that "I hope that the blood of my son Hamza is the last blood to flow of journalists as well as people in the Gaza Strip."

Air strikes also claimed civilian lives in the southern cities of Khan Younis and in Rafah where many displaced people have sought refuge.

The Israeli army – which claims to have "dismantled" Hamas's military leadership in northern Gaza – reported killing more "terrorists" in central Gaza, including in a drone strike in the Bureij refugee camp.

Israeli Prime Minister Benjamin Netanyahu vowed again at a cabinet meeting that "I have a clear message for our enemies: What happened on October 7 will not happen again.

"This is the commitment of my government and this is the reason why our soldiers in the field are giving their lives. We must continue until total victory."

The war started when Hamas on October 7 last year launched an unprecedented attack on Israel which resulted in about 1,140 deaths, most of them civilians, according to a tally based on official Israeli figures.

The militants, considered a "terrorist" group by the United States and the European Union, also took around 250 hostages, 132 of whom remain in captivity, according to Israel. At least 24 are believed to have been killed.

In response, Israel is carrying out a relentless bombardment and ground invasion that have killed at least 22,835 people, most of them women and children, according to the Hamas-run Gaza health ministry.

"These three months have been like a quarter of a century," said one Gaza resident, Nabil Fathi, 51. "I wake up thinking this is a passing nightmare, but it is a reality.

"Our home and my son's home have been destroyed and we have 20 people martyred in our family. I don't know where we will go even if I survive."

During the Gaza war, violence has also flared between Israel and Lebanon's Iran-backed armed group Hezbollah. They have traded almost daily cross-border fire, forcing Israel to evacuate communities near the border.

Hezbollah on Saturday said it had fired 62 rockets at an Israeli military base, days after it blamed Israel for a strike in Beirut that killed Hamas deputy leader Saleh al-Aruri.

The Israeli military said it had struck Hezbollah "military sites" in response, while army spokesman Daniel Hagari warned the Shi'ite Muslim armed group against "dragging Lebanon into an unnecessary war."

Netanyahu said Hezbollah should "learn what Hamas has already learned in recent months: No terrorist is immune.

"We are determined to defend our citizens and to return the residents of the north safely to their homes... If we can, we will do so diplomatically, and if not, we will work in other ways."

Blinken labelled the flareup in border hostilities a "real concern" and said "we want to do everything possible to make sure that we don't see escalation there."

On his fourth trip to the region since the October 7 attack, he visited Jordan on Sunday for talks with King Abdullah II.

The king warned Blinken against the war's "catastrophic repercussions" and of the need to end "the tragic humanitarian crisis" there.

The monarch also reiterated "the important role of the United States in bringing pressure for an immediate ceasefire in Gaza." (AFP)
