U.S. Mission to the United Nations

We represent the United States at the United Nations Since that time, USUN has served a vital role as the Department of State’s UN branch.

The United States Mission was created by an act of Congress to assist the President and the Department of State in conducting United States policy at the United Nations. Today, USUN has approximately 150 people on staff who serve to represent the United States’ political, economic and social, legal, military, public diplomacy and management interests at the United Nations.

NEW: Today, the UN Security Council sent a clear message to Hamas: Accept the ceasefire-hostage deal on the table.

Israel has already accepted this deal.

The fighting could stop today – and hostages could come home today – if Hamas agreed to the deal.

Today, I visited the Demilitarized Zone. It was a life-changing experience – and a reminder that as we link arms with allies in the fight for nonproliferation, human rights, and democracy, we must reaffirm that the way to achieve these ends is through diplomacy.

Today, the UN Security Council adopted a resolution to scale up humanitarian aid in Gaza.

This is a big deal, but we know that only progress on the ground can turn these words into action.

So the U.S. will continue to work with our partners to get more humanitarian aid to Palestinians in need.

To secure the release of all hostages being held by Hamas.

And to work towards a lasting peace.

Today, the UN Security Council adopted a resolution that calls for:

- The immediate and unconditional release of all hostages held by Hamas and other groups.

- Humanitarian pauses to allow for full, rapid, safe, and unhindered humanitarian access to civilians in Gaza.

- Parties to the conflict to comply with their obligations under international humanitarian law.

We support many of the important provisions the Council adopted, but we are deeply disappointed that a few Council members are still unwilling to condemn Hamas – or affirm the right of all Member States to protect their citizens from terrorist attacks.

As we speak, Palestinian children are fleeing the fighting in Gaza, crying out for help. As we speak, I...

I am outraged and horrified by the appalling unprovoked, brutal attacks by Hamas terrorists against Israel. The United States stands firmly with the Government and people of Israel – and unequivocally condemns Hamas’ violence against civilians.

When I spoke today with Israeli officials, I extended the United States’ heartfelt condolences for the lives lost, and reaffirmed our ironclad support for Israel’s security and right to self-defense. My team and I remain in close contact with our Israeli counterparts.
