Sources: Business in Africa and Togo public holidays. A national day of mourning can be expected for later this week in Togo, following the helicopter crash that killer Togo's Sports Minister, Atipe Kwako, and 18 Togolese nationals, mostly members of a delegation of Togolese sports officials, who had been attending the African cup of Nations football elimination match in which the Togo beat Sierra Leone 1-0 (none of the Togo football team were on board, though). We will continue to monitor further development, such as whether the day of mourning is declared a one-off public holiday.
Update: Late on Monday, Togo's President decreed three days of national mourning; during this period, flags will fly at half mast across the country, but no public holiday has been declared.
