A mosque where the Manchester Arena bomber worshipped denies encouraging people to "fight in any military struggle" following a BBC report.
A sermon by Imam Mustafa Graf at Didsbury Mosque in 2016 called for the support of fighters in Syria, according to two Muslim scholars.
It was delivered six months before Salman Abedi killed 22 people after an Ariana Grande concert.
Mr Graf declined to be interviewed but denied preaching Islamic extremism.
Didsbury Mosque said it had "launched an investigation into the sermon to identify any issues raised by the BBC report" as part of its regulations.
