An Islamic centre has been targeted by arsonists, in what police believe was an anti-Muslim attack. Leaders at the Har-low Islamic Centre say they're "very saddened" by the incident.
Robyn Dwyer reports.
Members of an Islamic centre which suffered a suspected overnight arson attempt have said they are "very saddened" by what appears to be an anti-Muslim attack.
Police believe the incident at Harlow Islamic Centre in Paringdon Road, Harlow, Essex, took place between 10.30pm and 4am.
There had been a "concerted effort" to start the blaze by sealing entrances with foam so the fire would take hold, a member of the mosque said. Zia Rehman, the Islamic Centre's vice-chairman, said he suspects it may have been due to anti-Muslim prejudice.
Britain has seen a spike of hate crimes against Muslims in recent months following the death of Fusilier Lee Rigby outside Woolwich Barracks in south east London in May.
