Kamala Harris, the US vice president, reiterated in Warsaw on Thursday that the US commitment to Article 5 of the Nato treaty is "ironclad."

Harris was speaking at a joint press conference with the Polish president, Andrzej Duda, after face-to-face talks.

Article 5 says that an attack on one Nato member shall be considered an attack on all of them.

"I've said it many times, and I will say it again: The United States' commitment to Article 5 is ironclad," Harris said.

"The United States is prepared to defend every inch of Nato territory," she added. "The United States takes seriously that an attack against one is an attack against all."

The US vice president also announced additional humanitarian aid for Ukraine.

She said the United States will give Ukraine another USD 50 million through the UN World Food Programme "to assist with humanitarian aid."

But the US will also support the broader region, Harris said.

"We are also pleased to have shared with the (Polish) President what the US Congress has done, which is that there is a commitment now of USD 13.6 billion in humanitarian and security assistance that will be then distributed and shared with Ukraine and the people of this region and Europe," the vice president said.

Poland has accepted close to 1.5 million refugees from Ukraine in the span of just two weeks. Poles have rushed to help their neighbours fleeing from the Russian invasion, offering them food, shelter, clothing and often a place in their own homes.
