The Ministry of Defense (MoD) said the airstrike was conducted in the past 24 hours but did not elaborate further.
It is yet not clear if the airstrike was conducted by the Afghan Air Force or the US forces based in Afghanistan.
Both the Afghan and US forces conduct regular airstrikes against the insurgents to suppress their activities amid deteriorating security situation.
The US forces in Afghanistan resumed airstrikes after they were granted broader role by the Obama administration earlier this year.
Helmand is among the volatile provinces in southern Afghanistan where the Taliban insurgents are actively operating in a number of its districts.
The group has launched numerous attacks in this province during the year with the local officials saying that the growing raids were aimed at establishing a council in this province.
However, the officials said the Afghan forces managed to repulse the Taliban attacks and thwarted their plans to shift some of their leadership council members to Helmand.
