Israel carried out deadly bombardments in Gaza for a second day on Saturday after a week-long truce with Hamas collapsed despite international calls for an extension.
Clouds of grey smoke from the strikes hung over Gaza, where the Hamas-run health ministry said nearly 200 people had been killed since the pause in hostilities expired early Friday.
Both sides blamed each other for breaking the truce, with Israel claiming that Hamas had tried to fire a rocket before it ended and that it failed to produce a list of further hostages for release.
"What we're doing now is striking Hamas military targets all over the Gaza Strip," Israel Defense Forces spokesman Jonathan Conricus told reporters on Saturday.
As hostilities resumed, Hamas's armed wing received "the order to resume combat" and to "defend the Gaza Strip", according to a source close to the group who asked not to be named because they were not authorised to speak to the media.
"I deeply regret that military operations have started again in Gaza," UN secretary-general Antonio Guterres said on X, formerly Twitter.
"Today, in a matter of hours, scores were reportedly killed and injured," UN humanitarian chief Martin Griffiths said.
"Families were told to evacuate, again. Hopes were dashed."
Fears of a wider regional conflict grew after the Syrian defence ministry said Israeli strikes had hit Damascus on Saturday and the militant group Hezbollah said one of its members had been killed in an Israeli strike on Lebanon on Friday.
"We're going to continue to work with Israel and Egypt and Qatar on efforts to reimplement the pause," US Defense Secretary Lloyd Austin told reporters in California on Friday.
Mediation efforts by Qatar and Egypt are ongoing, said a source briefed on the talks who asked not to be named.
'Mother of all thumpings'
During an unprecedented attack on October 7, Hamas fighters broke through Gaza's militarised border into Israel, killed about 1,200 people, mostly civilians, and kidnapped around 240, according to Israeli authorities.
Israel vowed to eliminate Hamas in response and unleashed an air and ground campaign that has killed more than 15,000 people, also mostly civilians, the Hamas authorities who run Gaza say.
Rockets are fired by Palestinian militants toward Israel as smoke billows from the southern Gaza Strip, on December 1, 2023, as fighting resumed shortly after the expiration of a seven-day truce between Israel and Hamas militants. A temporary truce between Israel and Hamas expired on December 1, with the Israeli army saying combat operations had resumed, accusing Hamas of violating the operational pause.

But in a diplomatic breakthrough, both sides agreed to a seven-day truce, during which Hamas freed 80 Israeli hostages in exchange for 240 Palestinian prisoners, and more aid entered Gaza.
The week of hostage-prisoner exchanges yielded tearful reunions of Israeli families with their released relatives and jubilation in the streets of the occupied West Bank as Palestinian prisoners walked free from Israeli jails.
Twenty-five other hostages, mostly Thais, were also freed in separate arrangements.
The Israeli army said Friday that five more hostages had died, bringing the total number to seven, and 136 were still being held, including 17 women and children.
US Secretary of State Antony Blinken told reporters in Dubai on Friday that the United States remained "intensely focused on getting everyone home, getting hostages back" and "pursuing the process that had worked for seven days" during the truce.
But Israeli government spokesman Eylon Levy told reporters: "Having chosen to hold onto our women, Hamas will now take the mother of all thumpings."
The Israeli military said that "ground, air and naval forces struck terror targets in the north and south of the Gaza Strip, including in Khan Yunis and Rafah."
Israeli forces carried out operations early Saturday in various areas of the occupied West Bank, according to the official Palestinian news agency Wafa.
Outside the Al-Ahli hospital in Gaza City, a man in a blue sweater bellowed in grief and turned his face and hands to the sky after viewing a dead boy in a body bag, AFPTV footage showed.
"What did he do wrong? God, what did we do to deserve this?" he yelled.
Guterres has warned of a "humanitarian catastrophe" in Gaza, where the United Nations says 1.7 million people are displaced and short of food, water and other essentials.
"The healthcare service is on its knees," Rob Holden, a World Health Organization (WHO) senior emergency officer, told journalists from Gaza as explosions were heard in the background.
On a bed at Khan Yunis's Nasser hospital, Amal Abu Dagga wept, her beige veil covered in blood.
"I don't even know what happened to my children," she said. A relative, Jamil Abu Dagga, told AFP the family had been at home when the bombs started falling.
In Israel, sirens warning of potential missiles sounded in several communities near Gaza. Authorities said they were restarting security measures in the area, including closing schools.
"Today, the Gaza Strip is once again the most dangerous place in the world to be a child," UNICEF's executive director Catherine Russell said in a statement Saturday.
The Israeli military published a map of "evacuation zones" in the Gaza Strip that it said would enable residents to "evacuate from specific places for their safety if required".
Israeli forces "will begin a crushing military attack on your area of residence with the aim of eliminating the terrorist organisation Hamas," the warnings said.
