Hundreds of students in the eastern Afghan city of Jalalabad have vented their anger at a film made in the United States that Muslims worldwide say insults the Prophet Muhammad.
Some 400 students blocked the main road leading to Kabul, shouting anti-U.S. slogans.
Local official Ahmad Zia Abdulzai said the road was only blocked for about an hour and added that some protesters burned pictures of "a Western country's leader."
Protests also took place in Kabul and the northern city of Konduz earlier this week expressing outrage at the low-budget film "Innocence of Muslims."
