A Muslim radio station broadcast lectures by an Al Qaeda terror leader calling for holy war.
Iman FM transmitted 25 hours of sermons from Anwar Al-Awlaki, a hate preacher killed by a US drone strike in 2011.
A complaint was made to Ofcom, which has suspended the Sheffield-based station’s licence.
The watchdog said the material ‘amounted to a direct call to action to members of the Muslim community to prepare for and carry out violent action against non-Muslim people’.
Bosses at Iman FM have 21 days to explain themselves or be closed down. They found the extremist lectures on YouTube and broadcast them during Ramadan.
Ofcom said Al-Awlaki, who was an American Muslim cleric of Yemeni descent, was an Al Qaeda leader, recruiter and trainer.
