The war erupted when Hamas-led terrorists stormed into southern Israel on Oct 7, 2023, killing some 1,200 people, mostly civilians, and taking 251 hostages. Most have been released in ceasefires or other deals, with Israeli forces rescuing only eight and recovering dozens of bodies.
The ceasefire deal that the U.S. helped broker, however, did not require Hamas to release more hostages to extend the halt in fighting beyond its first phase.
An Israeli official, speaking on condition of anonymity to discuss the unfolding operation, said Israel was striking Hamas' military, leaders and infrastructure and planned to expand the operation beyond air attacks.
The official accused Hamas of attempting to rebuild and plan new attacks. Hamas terrorists and security forces quickly returned to the streets in recent weeks after the ceasefire went into effect. Hamas on Tuesday denied planning new attacks.
