Kunduz: At least three demonstrators were killed on Saturday, medical sources said, as protesters tried to storm a UN compound in northern Afghanistan in a fifth day of violence over Quran burning.

Sahad Mokhtar, head of the public health department in Kunduz, said: "The report we have so far from hospitals is three killed, 47 wounded in today's demonstrations."

The UN complex in the city saw police firing at protesters to try to stop them entering the premises, while demonstrators burned tyres and traffic booths across Kunduz.
