Washington, Safar 25, 1436, Dec 17, 2014, SPA -- US President Barack Obama and Cuban President RaulCastro will attend the Summit of the Americas in Panama in April, ending a long-standing tiff within the Organization of American States (OAS). Unnamed White House sources confirmed that Obama would be at the April 10-11 summit, while Panamanian authorities said last week that Castro would be there. While Obama and Cuban President Raul Castro already shared an historic handshake last year at the funeral for South Africananti-apartheid hero Nelson Mandela, the Summit of the Americas would-be the first time they shared a political forum. --SPA 00:01 LOCAL TIME 21:01 GMT www.spa.gov.sa/w
