Israel's military said it had struck more than 600 militant targets in the past few days as it expanded ground operations in the Gaza Strip, where Palestinian civilians are in dire need of fuel, food and clean water as the war enters its fourth week.
"IDF troops killed dozens of terrorists who barricaded themselves in buildings and tunnels, and attempted to attack the troops," a military statement said.
Israel began a major push into Gaza on Friday and reiterated calls for civilians to move from the north of the tiny coastal enclave to the south as it tries to root out Hamas militants it says are hiding in a labyrinth of tunnels under Gaza City.
In what appeared to be an effort to cut off the city, Israeli forces carried out dozens of air strikes on its eastern side, residents said, with some reporting the roar of tanks rolling in early on Monday amid heavy exchanges of fire.
To the west, where Israel on Sunday showed tanks on the Mediterranean coast, the north-south coast road was hit several times, residents said.
Internet and phone connections remained largely cut off in the north, making communication difficult.
Israel began a major push into Gaza on Friday and is calling for civilians to move south.
Many Palestinians have remained in Gaza City, afraid to lose their homes and concerned by news of Israeli air strikes further south.
Medical officials in Al-Shifa and Al-Quds hospitals said air strikes had hit near their buildings.
The UN humanitarian office OCHR said 117,000 civilians are sheltering alongside thousands of patients and doctors in hospitals in the north.
Israel has accused Hamas of locating command centres and other military infrastructure in Gaza hospitals, which the group denies.
Air strikes could also be heard in the southern towns of Rafah near Gaza's border crossing with Egypt, as well as east of Khan Younis, where Palestinian media said Hamas clashed with Israeli troops.
Israel has said 1400 people were killed when Hamas-led militants stormed through the south of the country on October 7 and took 229 hostage.
Hamas has released four and said 50 had been killed in retaliatory strikes.
Israel's ground attacks on Gaza have spurred calls for a "humanitarian pause" to allow aid in.
Medical authorities in Hamas-run Gaza, which has a population of 2.3 million people, said on Monday 8306 people - including 3457 minors - had been killed.
Islamist groups Hamas and Islamic Jihad said their members were also fighting Israeli forces in the Israeli-occupied West Bank city of Jenin, where scores of Palestinians have been killed and hundreds arrested since October 7.
Israel said on Monday it had arrested 700 Hamas militants in the West Bank, where it says its forces often come under fire while trying to detain them.
The Palestinian health ministry said four people were killed during a raid in Jenin early on Monday. Israel said several fighters were killed in an air strike there.
The conflict has spurred large demonstrations worldwide in support of the Palestinians, and anti-Semitic and Islamophobic harassment and attacks are increasing.
Russian authorities said they had taken over an airport in the predominantly Muslim Dagestan region and arrested 60 people after hundreds of anti-Israel protesters stormed the facility on Sunday when a plane from Israel arrived.

Israel's widening ground attacks on Gaza have spurred international calls for a "humanitarian pause" to allow aid in.

OCHA said 33 trucks carrying water, food and medical supplies had entered Gaza on Sunday, the biggest delivery so far, but much bigger daily deliveries were required to meet urgent needs and prevent civil unrest.
