U.S. President Donald Trump has threatened to “destroy” Hamas if the group fails to comply with the ceasefire agreement signed with Israel, warning that a new offensive in the region could begin, CNN reports.

“If necessary, they will be destroyed — and they know it,” Trump said, warning that if the violence in Gaza continues, “we will step in and stop it, and it will happen very quickly and very harshly.”

Trump added that U.S. troops would not take part in any new military operations, noting that other forces are on the ground and ready to act if he determines that Hamas has violated the ceasefire.
