Congress president Sonia Gandhi has expressed 'outrage' over the publication of cartoons of Prophet Mohammed in European newspapers.

'The Congress party has the highest regard and respect for all faiths and is committed to protecting their rights and beliefs for preserving and strengthening the secular nature of our society,' she said in a letter to Syed Ahmed Bukhari, the Shahi Imam of Delhi's Jama Masjid.

'I have received your letter and share your sense of outrage about the publication of insensitive cartoons of the Prophet. The United Progressive Alliance government has conveyed its strong setiments to the government of Denmark through the Indian and Danish ambassadors in our respective countries,' the letter said.
