Barack Obama has officially been sworn in for his second term as US president in a small ceremony at the White House.
Although the US Constitution requires the oath of office to be taken by noon on 20 January, that falls on a Sunday so the public inauguration will take place on Monday.
Mr Obama took his official oath in the White House's Blue Room.
