The U.S. State Department said Saturday that it has “credible reports” that the Hamas terrorist group could violate the cease-fire with an attack on Palestinian civilians in Gaza.

If the attack takes place, it “would constitute a direct and grave violation” of the agreement forged by President Trump to end the two-year war between Israel and Hamas, the statement said.

No further details were disclosed about the potential attack.

A Hamas official on Friday defended the terrorist organization's recent killings of Palestinians in Gaza...

"This is a transitional phase," Hamas politburo member Mohammed Nazzal told Reuters.

"Civilly, there will be a technocratic administration as I said. On the ground, Hamas will be present."

...despite President Trump's warning to Hamas on Thursday on social media that “if Hamas continues to kill people in Gaza, which was not the Deal, we will have no choice but to go in and kill them.”

The U.S. president later clarified he won’t send U.S. troops into Gaza after launching the threat against Hamas.

Palestinians have warned Fox News and Reuters that the executions have not ceased so far, with at least 33 people killed in recent days, and Hamas said it could not commit to disarming itself amid the ceasefire.

”Should Hamas proceed with this attack, measures will be taken to protect the people of Gaza and preserve the integrity of the ceasefire,” the State Department said.

Israel blasted Hamas for its actions since the exchange of hostages for prisoners earlier in the week. 

“Hamas is supposed to release all hostages in stage 1. It has not. Hamas knows where the bodies of our hostages are. Hamas are to be disarmed under this agreement. No ifs, no buts. They have not. Hamas needs to adhere to the 20-point plan. They are running out of time,” said a statement from Prime Minister Benjamin Netanyahu's office.

HBO host Bill Maher confronted the sudden silence from college activists during Friday’s “Real Time with Bill Maher” as Hamas kills Palestinians in Gaza.

Maher asked guest Mark Cuban about the disappearance of “keffiyeh-wearing college kids” now that Hamas is “shooting everybody.”

“Where are the protesters?” Maher said. “Suddenly, the keffiyeh-wearing college kids are very quiet.”

Cuban agreed, responding “shooting everybody.” Maher repeated the phrase.
