Japan's defence minister Gen Nakatani has said a purported Islamic State video that seems to show the murder of hostage Kenji Goto "appears genuine".
The fight against Islamic extremism is a "generational struggle", Foreign Secretary Philip Hammond has said
Speaking during a visit to Australia, Hammond said it was "important" to recognise that "the underlying challenge of extremist Islamism is going to be with us for a long while".
"This is a generational struggle against this ideology and we are going to have to fight these battles, not just in the Middle East, but in other parts of the world as well," the Foreign Secretary said.
"There is no where that is safe from this challenge and we need to work together to be two or three steps ahead in the chess game," he added.
World leaders have condemned the murder of a Japanese journalist by Islamic State militants in Syria. Kenji Goto's killing comes less than a week after the death of another man from Japan held by the group. The country's Prime Minister has vowed not to 'give in to terrorism'.
