The U.S. increased pressure on Hamas on Tuesday to disarm in the next phase of an already fragile Gaza ceasefire as President Donald Trump pushed to cement an end to the devastating conflict.

In a visit to Israel, U.S. Vice President JD Vance said the ceasefire plan was going better than expected but warned the Palestinian militant group it would be obliterated if it did not cooperate, echoing a Trump threat earlier in the day of "fast, furious and brutal force."

Israel and Hamas have accused each other of repeated breaches of the truce since it came into effect 11 days ago, with flashes of violence and recriminations over the pace of returning hostage bodies, bringing in aid and opening borders. Israel has killed at least 87 Palestinians since the ceasefire began, according to the Gaza health ministry, and two Israeli soldiers were killed in southern Gaza over the weekend.
