Rihanna, Springsteen among stars to rock US Veterans Day

 A galaxy of big-name rock, pop and country artists, from Rihanna to Carrie Underwood, will honor members of the US military at a Veterans Day outdoor concert in Washington, organizers said Friday.
Bruce Springsteen, Rihanna, Eminem, Dave Grohl, Metallica, Underwood and the Zac Brown Band are among the acts lined up for the Concert for Valor on November 11.
Pay TV channel HBO said it would telecast the event live -- and without charge to viewers -- from the National Mall.
Also appearing will be Hollywood A-listers Meryl Streep, Tom Hanks and Steven Spielberg, "among many others," organizers HBO and Starbucks said in a statement.
Veterans Day in the United States marks the anniversary of the end of World War I.
News of the event comes as President Barack Obama takes America back into war, targeting the Islamic State group, after years of combat in Iraq and Afghanistan.
