The Russian-backed Chechen President Ramzan Kadyrov will inaugurate the "largest mosque in Europe" on October 17 in Chechnya, the Russian official news agency Novosty reported. Over 10,000 worshipers will be able to pray inside the mosque, which will be named after the president's father, Ahmad Kadyrov, who was killed in 2004. "The largest mosque in Europe... will by inaugurated on the first day of the International Peacemakers' Conference, titled 'Islam - Religion of Peace and Progress,'" the grand mufti of Chechnya, Sultan Mirzayev, told the press. Mirzayev underlined that approximately 50 countries have already approved their participation in the three-day conference. The building of the mosque began more than three years ago. Surrounding the mosque will be Chechnya's Islamic administration, a religious school, an Islamic university, a hotel and a religious library. Kadyrov, 31, is the son of Ahmad Kadyrov, an anti-Russian rebel leader who at one point was titled "Chechnya's rebel mufti" [mufti - an Islamic, cleric who issues religious decrees]. In 1999 the Kadyrovs defected to the Russian side. On March 2, 2007 then Russian president Vladimir Putin nominated Kadyrov as Chechen president.
