Australian PM Tony Abbott pays tribute at Anzac centenary

Australian Prime Minister Tony Abbott has told crowds at the Anzac centenary service that the men who left from "every rung of the ladder" became "the founding heroes of our modern Australia."

It is estimated more than 11,400 from Australia and New Zealand were killed in the fighting which followed.

Thousands of people from Australia and New Zealand are in Turkey for dawn ceremonies along with Princes Charles and Harry and a large number of international dignitaries.
