THE Archbishop of Canterbury, Dr Rowan Williams, condemned the "evil" atrocities carried out in London.
Speaking during a visit to the National Mining Museum, near Grange Moor, he said the events were appalling.
"I want first and foremost to extend my personal sympathy and condolences to everyone who is suffering and grieving at this time," he said.
"All those caught up in this tragedy and that includes of course the emergency services whose selfless dedication and commitment is so vital at times like this.
"All are in my prayers and in the prayers of a great many people."
The archbishop was at the museum for an inter-faith conference involving Christian and Muslim scholars.
Earlier he had been to the Medina Mosque in Purlwell Lane, Batley.
He said: "As it happens I have spent this morning with Muslim colleagues and friends here in West Yorkshire.
"We're all as one in our condemnation of these evil acts and in our shared sense of care and compassion of those affected in whatever way."
