President Barack Obama paid tribute Saturday to US war veterans, saying the nation must honor their sacrifice not just with words, but with deeds.

The president's radio address was aired in advance of the commemoration on Monday of Memorial Day, a national holiday set aside to honor those who fought for America in various wars since the country's founding.

Obama said that on Memorial Day, the country honored not just those who had worn US military uniform, but also the men and women who had died in defense of their fellow citizens.

And these soldiers deserved more than words, he said.

"We are called to honor them with deeds," said Obama.

"We are called to honor them by doing our part for the loved ones our fallen heroes have left behind and looking after our military families.

"By making sure the men and women serving this country around the world have the support they need to achieve their missions and come home safely.

"By making sure veterans have the care and assistance they need."

Obama asked Americans to commemorate Memorial Day by laying a flower in cemeteries across the country, where national heroes had come to rest.
