`October 7th `s strike of the United States and the United Kingdom in Afghanistan must be supported because it is an element in the fight against terrorism, a phenomenon incompatible with the Islamic religion,` Ibrahim Yalumov, Rector of the Higher Islamic Institute in Sofia said. `According to Islam, an attack against any one peaceful citizen of a country with which a given Islamic country maintains peaceful relations represents an attack against all mankind,` Yalumov added. `Terrorist organizations try to penetrate Bulgaria. If we fail to take due measures to prevent their spread, they will cause tensions,` Yalumov said. `Administrative measures by the Government must be complemented with measures by the Muslim community,` he added. Yalumov did not list terrorist organizations but said that the press recently has reported such cases. `Some of them have not been officially licensed to operate in Bulgaria, and others have moved out of the country,`according to him.
