The BBC's Paul Wood says the authorities in Kandahar have blamed the Taliban for the protests
Nine people have been killed in the Afghan city of Kandahar during a demonstration against the burning of a Koran in the US, officials say.
Hundreds of people took part in the protest. Gunfire was heard and cars were set on fire.
On Friday, seven UN workers were killed after a protest over the same issue in in the northern city of Mazar-i Sharif.
It was the worst attack on the UN mission in Afghanistan since the international invasion in 2001.
Further violence
A large and angry crowd surged through the streets of Kandahar, chanting "They have insulted our Koran" and "Death to America", the BBC's Paul Wood reports from Kabul.
The authorities in both Kandahar and Mazar-i Sharif blamed the Taliban for the attacks. However, the Taliban has rejected the accusation.
