The Ministry of Defense confirmed in a statement that reinforcements headed to the volatile Bala Murghab district in Badghis from the neighboring Herat province in the west of Afghanistan early on Friday morning.
The ministry said that the security forces have advanced in some parts of the district.
Taliban militants captured key parts of the Bala Murghab district late on Thursday night, including the municipality building and the main market of the district, sources acknowledged, adding that the Army base and the police headquarters remained under siege throughout the night.
Almost 500 troops are fighting an unknown number of Taliban militants in the district, said Abdul Aziz Beg, Head of Badghis Provincial Council.
Latest figures by local officials show that at least 36 members of the Afghan forces were killed in the clashes.
Other sources confirmed on Friday that airstrikes have started targeting Taliban militants in the district.
Jamshed Shahabi, a spokesman for Badghis governor, said the casualties of the Afghan forces are not as much high as reported.
He said that more than 30 Taliban militants have been killed in the clashes.
Last time, the district came under Taliban attack early in March and was under siege for more than two weeks, leaving more than two dozens of security forces dead and almost 28 of them gone missing.
This comes as the conflicts have intensified in different parts of the country with the arrival of the spring season – which is deemed as a usual fighting season for insurgents fighting the Afghan government forces.
President Ashraf Ghani on April 2 approved the annual security plan which encompasses boosting security and fighting insurgents.
