Zambia's opposition leader on by-election violence

In Zambia's north-west province counting of votes is underway following a key by-election which was marred by violence.

Both the ruling Movement for Multiparty Democracy (MMD) and the opposition have been blaming each other for political violence that has seen running battles between supporters having to be dispersed by police using tear gas.

The Mufubwe district by-election is being regarded as a key indicator of the country's political temperature ahead of next year's general elections.

Such was the importance of the polls that both President Rupiah Banda and senior opposition leaders were in the area to support campaigns.

Hakainde Hichilema is the president of one of the main opposition parties in Zambia - the UPND - the BBC's Peter Ndoro asked him what he made of the violence.
