Peres at 90

The Israeli President Shimon Peres is turning 90 - making him the oldest head of state in the world, decades older even than his own country. His own life mirrors the turbulent trajectory of the nation of Israel. For some he's the father of the nation, for others he's a divisive political figure. The BBC's Chief International Correspondent Lyse Doucet - who has been reporting from the Middle East for 20 years - meets Shimon Peres and looks back at the life of a man who played a defining role in both times of war and peace.
