The crisis between Iraq's central government and the autonomous Kurdish region is rooted in a long-standing dispute over territory stretching from the Syrian border to the frontier with Iran.

The reported death of Islamic State's top leader in Southeast Asia is a major blow to the jihadists but analysts warn it remains a potent threat, with battle-hardened fighters set to return from the Middle East.

Once the last Islamic State group fighters are ousted from Syria's Raqa, the unconventional forces battling the jihadists say they'll have batteries and masking tape to thank for their victory. 

Austria's hard-right Freedom Party has a shot at sharing power after elections on Sunday, having narrowly lost out in a presidential vote last year.
