Israel's assassination of a senior Hamas commander threatens the viability of the Gaza ceasefire, the chief negotiator of the militant group said on Sunday, calling on U.S. President Donald Trump to demand Israel comply with the terms of the truce.

On Sunday, Israeli forces launched air strikes and shelling across multiple areas of Gaza, violating the ceasefire. In Khan Younis, naval forces detained two fishermen and destroyed their boat, while artillery and air strikes hit eastern parts of the city, within the Israel-occupied yellow zone.

Aid deliveries into Gaza are falling short of the amount agreed upon in the U.S.-brokered ceasefire. That's according to an Associated Press analysis.

The next steps for the president’s 20-point Gaza peace plan have been mired in uncertainty and a lack of detail, but that may be set to change. Here’s what to know.

Israel carried out airstrikes, drone attacks, and artillery shelling across multiple areas of the Gaza Strip, killing several Palestinians.
