President Obama has been outlining his vision for a new chapter in the American foreign policy. Speaking to graduates of the United States military academy at West Point, he said the US must always lead on the world stage. The BBC’s Aleem Maqbool has more.

President Obama said he wanted to give his vision for the way America conducts itself on the world stage in a changing world.While he said the US reserved the right to carry out unilateral action where there’s an imminent threat to America, he focused on the shift towards building international consensus, particularly when it came to world problems that did not directly threaten the US.

“Our action should meet a simple test” he said, “We must not create more enemies than we take off the battlefield.”

President Obama has led tributes to the American writer, a civil rights activist and an academic, Maya Angelou who has died aged 86. He described her as one of the brightest lights of our time. The first volume of Angelou's biography I Know Why the Cage Bird Sings told her coming of age in an era defined racial segregation. She wrote frankly of being raped as a child and not speaking for 6 years when the rapist was killed after she named him. Born in Saint Louise, Missouri, she became one of America's foremost orators. Here she performs one of her own poems.
