President Trump said Thursday at the inaugural Board of Peace meeting at the U.S. Institute of Peace in Washington, D.C., that the group will be "looking over" the United Nations, and that a decision on Iran will be made in the upcoming days.

"The Board of Peace is going to almost be looking over the United Nations and making sure it runs properly," Trump said.

Trump invited dozens of countries to participate in the Board of Peace and help end the war between Israel and Hamas.

"The war in Gaza is over. It’s over," Trump said, adding that, still, "there are little flames."

"Hamas has been, I think they’re going to give up their weapons, which is what they promised," Trump said. "If they don’t, it’ll be, you know, they’ll be harshly met, very harshly met. They don’t want that."

The president explained that the U.S. would contribute $10 billion to the Board of Peace.
