The Israeli military spokesperson, Avichay Adraee, urged residents of four areas in Beit Lahia, in the northern Gaza Strip, to move to two specified shelter areas via a social media platform X post, stating, "You are in a dangerous combat zone."

He added that the army "will act very forcefully against the terrorist infrastructure and disruptive elements in the area."

The resurgence of aerial and artillery shelling in northern Gaza comes about four months after the Israeli military announced a reduction in its forces there, stating that Hamas no longer controlled those areas.

Israel withdrew most of its forces from southern Gaza this month. However, attempts to reach a ceasefire have failed, and Israeli shelling and airstrikes on areas from which its forces withdrew make it difficult for displaced Gazans to return to their abandoned homes.

Residents and media affiliated with the Palestinian Islamic Resistance Movement (Hamas) reported that army tanks re-entered east of Beit Hanoun at the northern edge of the Gaza Strip last night, but did not penetrate deeply into the city. Gunfire reached some schools sheltering displaced persons there.

The shelling today followed after warning sirens of incoming rockets in two southern Israeli towns, but there were no immediate reports of injuries.

The armed wing of the Islamic Jihad Movement claimed responsibility for the rocket attacks on Sderot and the kibbutz of Nir Am, indicating that the fighters are still capable of launching rockets after nearly 200 days of war that razed large areas of the Gaza Strip to the ground and displaced nearly all of its 2.3 million inhabitants.

Abu Ubaidah, a spokesperson for the Izz ad-Din al-Qassam Brigades, Hamas' military wing, said today that after 200 days of waging war, "the enemy is stuck in Gaza and will only reap disgrace and defeat."

In a statement to Al Jazeera, he called for escalating the conflict on all fronts and praised Iran's direct attack on Israel this month.

Abu Ubaidah said, "We call on all the masses of our nation to escalate the act of resistance in all its forms and on all fronts."

He added that Iran's response in magnitude and nature has set new rules and confused the enemy’s calculations.

He also stated that Hamas is adamant about its demands in the ceasefire talks that Israel permanently end its war, withdraw all its forces from Gaza, and allow displaced persons to return to northern Gaza Strip.

"We will not give up on the fundamental rights of our people, including withdrawal and lifting of the blockade, and the return of the displaced to their homes," he stated.

Israel rejects a permanent ceasefire, saying it would allow Hamas to reorganize its ranks.

Thick black smoke was seen rising in northern Gaza across the southern Israeli border. The shelling was intense around Beit Hanoun and Jabalia and continued on Tuesday morning in neighborhoods like Zaytoun, one of Gaza City’s oldest suburbs, where residents reported at least ten strikes within seconds along the main road.

*One of the Nights of Terror*

Umm Mohammed, a 53-year-old mother of six living 700 meters from the Zaytoun neighborhood, said, "It was one of the nights of terror we lived through at the start of the war. The tank and plane bombings did not stop."

She told Reuters via a chat application, "I had to gather with my children and my sisters who came to shelter with me in one place and pray for our survival while the house shook."

Medics reported that an airstrike targeted a mosque in western Beit Hanoun in Beit Lahia, killing a boy and injuring others, while a medic was killed in shelling near the city's stadium.

Another strike in Beit Lahia hit a crowd on the coastal road gathered to receive air-dropped aid. Reuters could not immediately verify this incident or whether there were casualties.

Elsewhere in the Strip, shelling in eastern Khan Yunis, the southern city's main area, followed a night of tank shelling in the area, and in the central area, four bodies were retrieved from a house hit overnight in the al-Nuseirat refugee camp.

The Israeli military said rockets fired at Israel overnight came from launch sites in northern Gaza. Rocket launchers and several militants were killed overnight in what the military described as "guided and precise strikes."

The statement read, "Over the past day, Israeli Air Force fighter jets and additional aircraft have struck approximately 25 terrorist targets across the Gaza Strip, including military infrastructure, observation posts, terrorists, and launch sites."

Israel claims it seeks to eliminate Hamas, which controls the Strip, following an armed attack by the group on October 7, which resulted in 1,200 deaths and 253 hostages, according to Israeli statistics.

The Palestinian health authorities reported that Israeli military airstrikes across the Gaza Strip killed 32 Palestinians and injured 59 others in the past 24 hours. They confirm that more than 34,000 people have been killed in the ongoing seven-month war, with thousands of bodies yet to be recovered.

At Nasser Hospital, the main health facility in southern Gaza, authorities retrieved another 35 bodies from what they say is one of at least three mass graves found at the site, bringing the total number of bodies found there to 310 in one week.

Palestinians say Israeli forces buried bodies there with bulldozers to hide crimes. The Israeli military stated its forces had exhumed the bodies at the site and reburied them after examining them to ensure no hostages were among them.

Israel claims it was forced to fight inside hospitals because Hamas fighters were operating there, a claim denied by medical staff and Hamas.
