Three military officials told the newspaper that the rockets are believed to have been launched by the Taliban in what essentially constituted a violation of the peace deal between the movement and Washington.
A Taliban commander has denied the movement's role in the attacks and promised the group would look into the matter, the newspaper added. The US-led mission to Afghanistan has refrained from commenting on the situation.
In late July, approximately a dozen rockets landed in the area surrounding Camp Bastion, an airbase used jointly by US and Afghan forces. A similar incident took place in late August with several rockets launched against nearby Camp Dwyer.
On 29 February, the United States and the Taliban movement signed a peace deal in the Qatari capital of Doha, stipulating a retreat of foreign troops from Afghanistan in return for guarantees of it not turning into a refuge for international terrorists.
