Minister of Islamic Affairs, Endowments, Call and Guidance Sheikh Saleh Al Al-Sheikh left here today for Sarajevo to participate in a ceremony due to be organized on the tenth anniversary of the mass annihilation which took place in two Bosnian cities in mid- nineties. The participation of the Kingdom of Saudi Arabia comes in response to an invitation from Bosnian President Sulejman Tihic. It is worth mentioning that the Kingdom was one of the pioneering countries as regards extending assistance to the Bosnians.
