Several rockets were fired at Kabul's airport on Monday, reports said quoting witnesses and security sources.
This come less than 48 hours before the United States is due to complete its troop withdrawal from Afghanistan.
News agency AFP reported that its staff heard the sound of rockets whooshing over the Afghan capital before the morning rush hour began.
A security official who worked in the earlier Afghan administration said the rockets had been fired from a vehicle in north Kabul.
The sound of the airport's missile defence system could be heard by local residents, who also reported shrapnel falling into the street -- suggesting at least one rocket had been intercepted, reports said.
Smoke could be seen rising above buildings in the north, where the Hamid Karzai International Airport is located.
