Israel Intensifies Gaza Strikes After Halt in Iran Operations as Military Warns of Hamas Rebuilding

Casualties rise in Gaza and monitoring groups record a sharp uptick in Israeli operations amid stalled moves toward a lasting settlement

By Leila Farooq

Since pausing joint strikes with the United States in Iran on April 8, Israel has focused renewed firepower on Gaza, where the military says Hamas is rearming and consolidating control. Palestinian health authorities report 120 deaths in Gaza during the five weeks since the pause, a rise of about 20% compared with the previous five-week period. Conflict monitoring group ACLED documented a 35% month-on-month increase in Israeli attacks in April. Progress toward a permanent settlement, which would see Israeli forces withdraw, militants disarmed and reconstruction begin, remains stalled.

Israel Intensifies Gaza Strikes After Halt in Iran Operations as Military Warns of Hamas Rebuilding

Key Points

  • Since April 8, Israeli operations in Gaza have increased, with the Gaza Health Ministry reporting 120 Palestinians killed in that five-week span, including eight women and 13 children; this is about 20% higher than the prior five weeks when Israel was conducting strikes over Iran.
  • ACLED recorded a 35% month-on-month rise in Israeli attacks in Gaza in April, citing roughly 30 separate incidents targeting militants, police and security installations in areas under Hamas control.
  • Progress toward a permanent settlement that would withdraw Israeli troops, disarm militants and begin reconstruction has stalled; sectors most directly implicated by these dynamics include defense and security, reconstruction and humanitarian assistance.

Overview

In the five weeks following a pause in joint Israeli-U.S. strikes in Iran on April 8, Israeli forces have markedly increased operations inside the Gaza Strip, redirecting their activity toward the devastated enclave. Palestinian health authorities report that 120 people were killed in Gaza in that period, including eight women and 13 children, a figure the Gaza Health Ministry says is about 20% higher than in the five weeks when Israel was carrying out sorties over Iran.


Monitoring groups and casualty figures

Conflict monitor ACLED, which tracks violence in the region, said in its monthly report for April that Israeli attacks in Gaza rose by 35% compared with March. ACLED data, according to a researcher with the group, shows that over roughly 30 separate incidents in April, Israel struck targets linked to Hamas, other militant groups, police personnel and police stations, as well as security checkpoints.

Since an armistice reached in October halted major fighting after two years of war, the enclave has remained largely ruined. ACLED and health ministry figures count some 850 Palestinians killed in Israeli strikes since that October ceasefire, without distinguishing between combatants and civilians. Over the same period, four Israeli soldiers were killed by militants. Hamas has not disclosed figures for its own fighter casualties.


Targets, tactics and immediate drivers

Several of the strikes since the Iran pause have hit positions associated with the Hamas-run police force. Health and police officials say at least 14 police officers were killed in Gaza since April 14. ACLED’s researcher noted that many of the April incidents occurred in areas under Hamas control, with Israeli shelling, drone strikes and gunfire continuing near the armistice line and targeting both militants and civilians, including women and children, approaching soldiers.

Israeli officials have signalled concern about Hamas rebuilding. Four Israeli defence officials told reporters in recent weeks that the military had warned the government that Hamas fighters were tightening their grip in Gaza and reconstituting weapons and forces. A separate Israeli military official, speaking on condition of anonymity, said the ceasefire allows Israel to act against imminent threats and that the military had prepared contingency plans for a possible resumption of larger-scale operations in Gaza, though no order for such a campaign had been issued.


State of the ceasefire and ground reality

The agreement reached in October ended major combat in Gaza but did not deliver a permanent resolution. Plans to withdraw Israeli troops, disarm militants and reconstruct the enclave have made only fitful progress. Israeli forces continue to occupy more than half of Gaza’s territory, where many of the remaining buildings have been demolished and residents were ordered to leave. More than 2 million people now live in a narrow coastal strip, largely in damaged structures or makeshift tents. In much of the territory, Hamas fighters exercise de facto control.

Residents say the ceasefire has not brought a halt to daily dangers. "The war is still ongoing," said Lafi Al-Najjar, 36, a blind Palestinian whose son was killed on April 28 in an Israeli strike. "It stopped in the announcement, but in reality and on the ground, the war has not stopped." Najjar and his family are living in a tented encampment amid the ruins of Khan Younis.


Regional operations and separate ceasefires

Since Israel began operating in tandem with the United States against targets in Iran in March, its military activity across the region has been intense. That campaign included a ground invasion and an air campaign in Lebanon against Hezbollah, the Iran-aligned movement. Fighting in Lebanon has eased under a separate U.S.-brokered ceasefire, but has not come to a full stop.


Implications and outlook

Despite the public halt to operations in Iran, the pattern of strikes in Gaza underscores that the October armistice has not yet produced a durable peace or a reliable pathway to reconstruction. Israeli officials’ assessments that Hamas is rebuilding its capabilities, combined with the military’s preparations for broader contingencies, leave the ceasefire fragile. The humanitarian toll continues across densely populated areas where people remain displaced and civilian infrastructure lies in ruins.

Reporting on casualty figures and incidents in Gaza draws on statements from the Gaza Health Ministry, ACLED’s monthly reporting, and comments from Israeli defence and military officials made in recent weeks.

Risks

  • The military assessment that Hamas is rebuilding capabilities introduces the risk of renewed wider fighting if authorities conclude a broader campaign is necessary - this principally affects defense and security sectors.
  • Continued strikes and occupation-related demolition prolong civilian displacement and infrastructure damage, impeding reconstruction and humanitarian operations and raising risks for reconstruction and aid sectors.
  • Fragility of the ceasefire and stalled political steps toward a permanent settlement create uncertainty for any long-term recovery plans, which may complicate planning for reconstruction contractors and international aid agencies.
