The 1st picture shows the minaret on el-Qal'a island in 1909, photographed by Gertrude Bell (courtesy of the Gertrude Bell Project), the 2nd photo (from the The Threat to World Heritage in Iraq web site) depicts it after restoration but before the building of the dam, the 3rd one (from Aljazeera.net) in its current condition after the attack: it's pretty much destroyed. The explosion took place on june 22. The Iraqi Accord Front, a mainly Sunni Arab Islamist Iraqi political coalition, accuses Shi'ites of staging a deliberate campaign of destroying national and esp. Sunni-origin monuments: the top of the Malwiyyah minaret in Samarra (also a famous monument built by a Sunni dynasty, this time the Abassids), the monument of el-Mansur in Baghdad, etc.
