Somalia’s groundbreaking presidential election moved into a second round on Wednesday as the number of candidates dropped from 21 to three, while a security lockdown closed the capital’s international airport and cleared major streets. Incumbent President Hassan Sheikh Mohamud held a slight lead over former prime minister Mohamed Abdullahi Farmajo, 88 votes to 72. With at least one of the remaining candidates having dual citizenship, Somalia could end up with a president who also holds a US passport, Farmajo.
