The Israeli military expanded its ground offensive into Gaza's refugee-crowded south on Monday while Israeli bombing continued to kill and injure dozens of Palestinians.
The renewed attack followed the end on Friday of a seven-day pause in the fighting between Israeli forces and Hamas which had allowed an exchange of 105 hostages held by Hamas, most of them Israelis, for 240 Palestinian prisoners.
The latest violence took place despite calls from the United States – Israel's closest ally – for Israel to limit harm to Palestinian civilians in the new phase of its offensive, focused on the south.
Gaza residents said Sunday they feared an Israeli ground offensive on the southern areas was imminent. Tanks had cut off the road between Khan Younis and Deir al-Balah in central Gaza, effectively dividing the Gaza Strip into three.
On Monday morning, Israel's military posted to X a statement with new orders to Gazans to evacuate about 20 areas or blocks in the Gaza Strip, with three arrows on the map all pointing south indicating where people should go.
Israel says it is defining "safe areas" for Gaza civilians to minimize harm to them but U.N. officials and people in Gaza say it is difficult to heed these orders in real-time given patchy internet access and unreliable electricity.
Lebanon-based Hamas official Osama Hamdan said on Sunday: "There are no safe areas."
Bombardments from warplanes and artillery were also concentrated on Khan Younis and Rafah, another city in Gaza's south, residents said, and hospitals were struggling to cope with the flow of wounded.
Israel government spokesperson Eylon Levy said the military had struck more than 400 targets over the weekend "including extensive aerial attacks in the Khan Younis area" and in Beit Lahiya in the north.
There was no immediate comment on the reports of specific attacks.
Widespread violence
On Sunday, Hamas said its fighters clashed with Israeli troops about 2 kilometers (1 mile) from the southern city of Khan Younis.
"The IDF (Israel Defence Forces) continues to extend its ground operation against Hamas centers in all of the Gaza Strip," Israeli military spokesperson Rear Adm. Daniel Hagari told reporters in Tel Aviv.
Israel said Monday its military death toll from ground operations in Gaza had risen to 76.
Early Monday, Hamas media quoted emergency services as saying an Israeli strike killed three civil emergency workers in Gaza City in the north of the coastal enclave.
The Jabalia refugee camp in the north of Hamas-ruled Gaza was among the sites reported hit from the air Sunday.
A Gazan Health Ministry spokesperson said an Israeli airstrike killed several people.
Footage obtained by Reuters showed a boy covered in grey dust, sitting weeping amid crumbled cement and rubble from collapsed buildings.
"My father was martyred," he cried in a hoarse voice. A girl in a pink sweatshirt, also coated with dust, stood between piles of rubble.
Shipping attacks
Attacks on shipping in the southern Red Sea on Sunday heightened fears of the conflict spreading.
The U.S. Defense Department said three commercial ships were attacked by Yemen's Iran-allied Houthi movement in international Red Sea waters, and a U.S. destroyer operating in the area shot down three drones as it responded to distress calls.
A Houthi spokesperson said its navy had attacked two Israeli ships in the Red Sea with an armed drone and a missile on Sunday though an Israeli military spokesman said the two ships had no connection to Israel.
More than 15,523 people have been killed, according to Gaza's health ministry, in nearly two months of warfare that broke out after the Oct. 7 Hamas incursion. In comparison, Israeli casualties are around 1,200.
