An Israeli air strike killed four Palestinians in Gaza, the territory's civil emergency service said, as Arab mediators and the United States tried to hammer out differences between Hamas and Israel over a January 19 ceasefire agreement.

The announcement signaled a breakdown in the Israel-Hamas ceasefire deal, the first phase of which expired Saturday with no clear next steps.

Israel said Sunday it has stopped the entry of all humanitarian aid into Gaza after phase one of its ceasefire deal with Hamas expired, citing the militant group’s refusal of a US-backed extension.

The first phase of the ceasefire deal between Israel and Hamas ended over the weekend amid Israel’s decision to suspend aid deliveries to Gaza until Hamas agrees to the U.S. ceasefire extension deal.
