Violence hits Uganda after early vote results

Violence erupts in Uganda as the initial results of a presidential election show the ruling party candidate Yoweri Museveni is in the lead.

Heavily-armed police on Friday surrounded the headquarters of the main opposition party and fired tear gas from a helicopter to disperse a crowd.

Police detained the main opposition presidential candidate Kizza Besigye in the capital Kampala, raising tensions amid mounting allegations of vote rigging in elections.

According to the initial tally, the 71-year-old contender from the ruling National Resistance Movement has garnered 63 percent of the votes so far.
