IS hostage David Haines's brother Michael in tribute video

Hostage David Haines's brother Michael has paid tribute to the aid worker who was killed last month.

He said the former RAF aircraft engineer who was killed by the Islamic State (IS) group, was an "ordinary guy from Perth... and we grieve for him every day".

David Haines was a selfless man, his brother said: "Much like we'd cross the road to help a neighbour, David saw the whole world as his neighbour."
