MDC Alliance under lockdown

Zimbabwean riot police officers stand guard in front of the headquarters of the opposition party Movement for Democratic Change (MDC) in Harare.

Zimbabwe is on edge awaiting the results of its historic presidential election after troops opened fire on protests against alleged electoral fraud, denting hopes of a new era for the country following the ousting of Robert Mugabe.

The government late on Wednesday vowed to enforce a security crackdown to prevent further unrest after the army opened fire to disperse opposition protests in Harare, leaving at least three people dead.
