Zambian police officers apprehend a supporter of the opposition United Party for National Development party outside the Presidential Election result centre at Mulungushi International Conference Centre in Lusaka on January 21, 2015. Zambian police fired teargas to disperse around 100 supporters of the leading opposition candidate in Zambia’s presidential elections on January 21 as they waited for results of the vote. Some 21,00 voters in dozens of polling stations were expected to cast ballots on January 21, after presidential elections were extended for a second day, in a hotly contested presidential election to replace Michael Sata, who died in office last year.
