A peace agreement between Gaza and Israel is under threat after reports of a "planned attack by Hamas".
In a statement issued on Saturday, the US Department of State said the US government had learnt of the "credible reports" indicating "an imminent ceasefire violation by Hamas against the people of Gaza".
The peace deal, struck on October 9, led to Israeli soldiers partially withdrawing from Palestinian territory before thousands of detainees were exchanged for Israeli hostages.

"This planned attack against Palestinian civilians would constitute a direct and grave violation of the ceasefire agreement and undermine the significant progress achieved through mediation efforts," the statement reads.
"Should Hamas proceed with this attack, measures will be taken to protect the people of Gaza and preserve the integrity of the ceasefire."
The department added that guarantors for the peace agreement, including Egypt, Qatar and Turkey, have been notified of the potential attack.
"The guarantors demand Hamas uphold its obligations under the ceasefire terms," the statement reads.
"The United States and the other guarantors remain resolute in our commitment to ensuring the safety of civilians, maintaining calm on the ground, and advancing peace and prosperity for the people of Gaza and the region as a whole."
No further details were disclosed about the potential attack.
US President Donald Trump warned Hamas on Tuesday to lay down their weapons in "a reasonable period of time" or face consequences.
"If they don't disarm, we will disarm them, and it will happen quickly and perhaps violently," Trump said. "But they will disarm."
It also comes as US Vice President JD Vance plans to travel to Israel alongside special envoy Steve Witkoff on Monday to discuss the second phase of the peace deal.
