美国纪念阵亡将士日

Americans are pausing Monday to honor the country's war dead, as the United States observes its annual Memorial Day.

U.S. President Barack Obama is taking part in a wreath-laying ceremony at Arlington National Cemetery, just outside Washington, before giving an address remembering those who gave their lives for the country.  Soldiers have placed American flags on more than 260,000 graves at the cemetery.

Mr. Obama and his wife, Michelle, also hosted a breakfast at the White House for families of the fallen.
