WASHINGTON: The U.S. House of Representatives is urging five countries to speed up the opening of a secret Nazi archive that documents the lives and deaths of millions of World War II concentration camp inmates.

In a resolution passed with bipartisan support Wednesday, the House urged the international commission that controls access to the archives ratify changes in a 1955 international agreement on the management of the files to make them public.

The U.S. Senate passed a similar resolution earlier this month.
