BRUSSELS (AP) The United States will expand its sanctions on Russia in response to the invasion of Ukraine, targeting members of the countrys parliament and the central banks gold reserves, the White House announced Thursday.

At the same time, Washington will increase its humanitarian assistance by welcoming 100,000 Ukrainian refugees and providing an additional $1 billion in food, medicine, water and other supplies.

The White House announced the initiatives as U.S. President Joe Biden and world leaders gathered in Brussels for a trio of summits in response to the Russian invasion, seeking new ways to limit the economic and security fallout from the conflict.
