Hillary Clinton has begun on a promotional tour for a book in which she defends her time as the US secretary of state.
Analysts say the book's content, and the tour, is an attempt to lay the groundwork for a second run at the presidency.
Clinton says she differed with the US president, Barack Obama, on policies including Egypt and Syria.
