It was a violent day across Gaza and the West Bank.

Palestinians say Israeli strikes that hit a United Nations school-turned shelter killed dozens in Gaza.

The UN said six of its staff died in the attack.

In the West Bank, an Israeli soldier died when a Palestinian truck rammed a bus stop,

and Palestinians say Israeli raids backed by airstrikes killed at least five.

Nick Schifrin looks at the ongoing violence starting in Gaza.

At this school-turned shelter today,

the aftermath was too much to bear and too graphic to show.

Survivors collected body parts in whatever they could carry.

After a bomb gutted the bedroom that had once been a classroom.

Israel said the target was Hamas militants planning attacks.

Palestinians said among the dead displaced women and children.

Israel has pushed the displaced to all Muassee,

where early yesterday morning

first responders dug through soft sand

in the crater left by an Israeli bomb.

By day, three craters, each at least 40 feet wide,

suggested Israel had dropped large bombs on what Israel

calls a safer zone, tents that lead to the sea and have become a sea of humanity.

The bombs blew through flimsy canvas and left behind the artifacts of a family's displaced

life.
