The photographs, which show the destruction in Mosul, Iraq's second largest city, and the town of Tal Afar, were posted on a website which frequently carries official statements from the Islamic State extremist group.Some of the photos show bulldozers plowing through walls, while others show buildings being demolished by explosives in a cloud of smoke and rubble.Residents from both Mosul and Tal Afar confirmed the destruction of the sites, Associated Press has reported.Sunni extremists consider Shia Muslims heretics, and the veneration of saints apostasy.A Twitter feed attributed to Isis, which reportedly carried the images, described the buildings as pagan 'temples', according to The Times.'We feel very sad for the demolition of these shrines, which we inherited from our fathers and grandfathers,' Ahmed, a 51-year-old Mosul resident, said, the Times of India reported.He added: 'They are landmarks in the city.'Security agencies in Iraq, meanwhile, were yesterday working to verify the authenticity of a video that purportedly shows the leader of Islamic State delivering a sermon at the Great Mosque in Mosul.(dailymail.co.uk)Bakudaily.az
