Tens of thousands of Palestinians waited, blocked on the road, to return to their homes in northern Gaza on Sunday, voicing frustration after Israel accused Hamas of breaching a ceasefire agreement and refused to open crossing points.

Palestinians are unable to return to their homes as Israel refuses to open crossing points, accusing Hamas of breaching the ceasefire.

Hamas released four female Israeli hostages on Saturday, in a second round of exchanges between Israel and Hamas which also saw around 200 Palestinian prisoners released from detention.

The Oct. 7 cross-border attack led by Hamas killed some 1,200 people, mostly civilians, and took around 250 others hostage. More than 100 were freed in a weeklong truce the following month. Israel believes at least a third of the over 90 captives still in Gaza are dead.

Young female “spotters” for Israel’s army reported suspicious activity across the border. When Hamas attacked, 15 were killed and seven abducted. Four came home on Saturday.

With a ceasefire agreement pausing the war between Israel and Hamas, Israeli troops have withdrawn from Gaza city centers. For the first time in eight months, NPR got a glimpse of Rafah this week.
