Protesters in Sudan are trying to imitate the Arab Spring uprisings that shook the region in 2011, President Omar al-Bashir said on Sunday during a visit to Egypt.Bashir is facing the most sustained challenge since he came to power in a coup in 1989. Demonstrators have turned out almost daily across the country to call for an end to his rule.Bashir's trip to neighboring Egypt is his second foreign visit since unrest began on Dec. 19. He has also visited Qatar.Speaking next to his Egyptian counterpart Abdel Fattah al-Sisi, Bashir blamed unidentified "harmful organizations" for working to destabilize the region."We do not claim there is no problem, but it is not of the size or dimensions that some of the media portray.""This is an attempt to copy the Arab Spring in Sudan, these are the same slogans and appeals and the very wide use of social media sites."
