Koran burning fuels further violence in Afghanistan

Nine people have been killed in an attack on an airport in Afghanistan.

It follows a week of violent protests after copies of the Koran, Islam's holy book, were burnt by US soldiers.

Muslims consider the Koran to be the word of God and treat each book with deep respect.

The American military has apologised for the burning of the books at its Bagram army base, saying it was a mistake but violence continues.

More than 30 people have been killed in the past five days.
