At least three people have been killed in a suicide car bomb attack at Jalalabad airport in eastern Afghanistan, police say. They say several other people were injured when the bomb exploded at the gates of the airport.
NATO troops have sealed off the area, said provincial spokesman Ahmad Zia Abdul Zai.
Afghanistan has seen days of deadly protests following the burning of Muslim holy books at a US base.
All the casualties at the airport appeared to be civilians, said provincial police official Obaidullah Talwar. The airport serves both civilian and international military aircraft.
