The families of two British aid workers murdered by Islamic State are calling on all religions to unite against the militants.
The brother of David Haines and wife of Alan Henning have issued a joint statement saying they will not allow the actions of the few to undermine the unity of people of all faiths.
Michael Haines has also posted a video paying tribute to his brother ahead of a memorial service in Perth later:
David Haines had been helping refugees in Syria in a camp near the Turkish border when he was snatched by IS militants last year. IS released a video showing his murder last month.
Michael Haines will address family, friends and colleagues at a service in the Scottish city, where David Haines grew up, later today.
The wife of murdered British hostage Alan Henning has also appealed for people to come together to stand against terrorism.
In a joint letter with Michael Haines, published in the Guardian newspaper, Barbara Henning said: "We condemn those who seek to drive us apart and spread hatred by attempting to place blame on Muslims and the Islamic faith for the actions of these terrorists."
The pair both said they had been overwhelmed by messages of support from the British public and people all over the world.
