The lead Hamas negotiator for ceasefire talks late today offered a deal to swap all hostages held in Gaza for an agreed-upon number of Palestinians jailed in Israel as part of a larger agreement to end the war.

The offer came after Hamas reportedly rejected the latest Israeli proposal for an exchange and ceasefire.

In the meantime, Israeli airstrikes overnight killed at least 27 Palestinians,

including 15 children, as the lack of aid into the enclave threatens hundreds of thousands.

Nick Schifrin reports, and a warning, images in this story are disturbing.

In Gaza, war spares no one.

Too young to comprehend, yet forced to suffer its cruelty.

The Abu Amshya brothers were injured in last week's strike on Gaza city's Shujayah neighborhood.

Israel said the target was a senior Hamas commander.

Palestinian officials say 30 people died, including eight children, many from the Abu Amshah family.

I got a call that my daughter-in-law's home was hit.

Why?

Everyone in that building was women and children, all women and children. I came

Amidst that rubble, rescue workers dig for survivors. Some pinned down by thousands of

pounds of collapse concrete.

But mostly the victims were buried in their homes.

In central Gaza on Sunday, Ibrahim Abu Muhadi lost six sons.

The family says an Israeli air strike hit their car.

Israel says it targeted a Hamas commander.

A 10-year-old boy went out to help his brothers so that they could get food to eat in the shadow of this siege.
