US President Barack Obama will attend a memorial service Sunday to honour the victims of Monday's shooting rampage at Washington Navy Yard, a White House spokesperson said.

 

 "I think the president will want to mourn the loss of these innocent victims and share in the nation's pain in the aftermath of another senseless mass shooting," reported Xinhua citing Jay Carney at a daily briefing.

 

 The shooting rampage occurred inside a building at the Washington Navy Yard which serves as the headquarters of the Naval Sea System Command. Thirteen people, including the suspect, were killed in the shooting.
