Eleven people have been injured as thousands joined a protest in Afghanistan against a US pastor's plan to burn the Koran.
Police in the northern province of Badakhshan said several hundred of the demonstrators ran towards a Nato compound where four attackers and five police were injured in clashes. Protesters burned an American flag at a mosque after Friday prayers.
Police in Farah province in the west said two people were injured in a protest at another mosque.
Terry Jones from the Dove Outreach Centre in Florida triggered outrage by announcing he would burn the Koran on the anniversary of the September 11 terror attacks.
On Thursday, he agreed to cancel the book-burning after claiming to have had assurances that a proposed mosque in New York would be moved away from the site of the 2001 terrorist attacks.
But he later claimed he had been "lied to" and said the protest, initially planned for September 11, had only been postponed.
He now says he will not burn the Koran if he's able to meet with the organisers behind the New York mosque on Saturday.
Speaking to NBC's Today show in the US, Mr Jones said if he meets with the imam in New York, he won't burn the Koran - but it wasn't clear if he meant the burning would be halted indefinitely or just for Saturday.
