CAIRO, EGYPT — Former Egyptian army chief Abdel Fattah el-Sissi secured a landslide victory in the country's presidential vote last week, the election commission confirmed on Tuesday. Turnout was about 47 percent of Egypt's 54 million voters, the commission said - less than the 40 million votes, or 80 percent of the electorate, that Sissi had called for. Meanwhile, Egypt has invited Iranian President Hassan Rouhani to the inauguration ceremony of newly elected Sissi, a trip that would make him only the second Iranian leader to visit Egypt since the countries severed ties in 1980.
