According to the BBC, "Muslim leaders are writing to hundreds of mosques appealing for help in finding the London bombers. Warning Muslim neighbourhoods could face a backlash, the Muslim Council of Britain (MCB) said police had increased patrols near places of worship. There have been reports of vandalism to mosques in London, the West Midlands and Merseyside.

"The MCB received approximately 30,000 hate e-mails immediately after the bombs. An analysis of the mail has led the organisation to believe it could be the work of just a small number of people who launched a "denial of service" computer program designed to crash the MCB's website."
