ITV News Middle East correspondent Julian Manyon shows just how difficult it can be to gain access at the African Union Assembly in Sharm-el-Sheikh, Egypt.

The congress, the eleventh of its kind was notable due to the attendance of Zimbabwean president Robert Mugabe.

Africa’s heads of state met to discuss issues bedevilling the continent such as water, sanitation and rising food prices.

The African Union's top diplomat said the continent must shoulder its responsibilities and help both sides of Zimbabwe's political divide overcome their differences after an election crisis.

Chairman of the African Union Commission, Jean Ping, said: "Africa must fully shoulder its responsibilities and do everything in its power to help the Zimbabwean parties to work together to help overcome their country's problems."
