Turkey's largest city, Istanbul, remains on edge after Saturday's suicide bombing that was blamed on Islamic State terrorists. Dorian Jones reports.
"Fear continues to stalk Istanbul. Some parents kept their children away from school to avoid them having to use service buses. People are also avoiding public spaces amid fears of further attacks. Turkish President Recep Tayyip Erdogan says his government is doing its utmost to confront the danger. On Sunday one of the biggest events on the country's sporting calendar, a match between Istanbul's top football teams, was canceled. The decision was made just hours before kickoff by the city governor, who cited what he said were credible intelligence warnings of another attack. Dorian Jones, Istanbul."
