Muslim leaders condemned the "heinous and appalling" Westminster terror attack as they joined together with Christian and Jewish leaders just metres from the scene of the atrocity.
Sheikh Mohammed Al-Hilli, representing Shia Muslims, and Sunni Sheikh Khalifa Ezzat, head Imam at the London Central Mosque, stood side-by-side with Justin Welby, Ephraim Mirvis and Cardinal Vincent Nichols outside Westminster Abbey.
They led a minute of silence in tribute to the four innocent victims who were killed and the many who were left injured.
