Reiforcements have been deployed in the Sangin district, Helmand province in southern Afghanistan, where reports say the situation seems bleak with the district being taken over by Taliban forces.
Zabihullah Mujahid, a Taliban spokesperson, said the Taliban flag has been unfurled there, and the military and police buildings are under its control.
The Afghan defence ministry, however, refutes the claim stating that the fighting is still going on with reinforcements deployed.
"We are still fighting to push back the Taliban. Parts of Sangin are under the Taliban control but not the police and military installations," Helmand's deputy governor, Mohammad Jan Rasoolya told Al Jazeera.
"The military planes have dropped food and supplies to the Afghan forces on ground."
The fighting between Afghan troops and Taliban forces has been escalating for a week, and on Thursday, reports trickling in from the area hinted at a Taliban victory.
The police headquarters and the main government building fell into the mujahideen's hands on Wednesday, a local Afghan senator was quoted as saying by BBC.
"As part of the UK's ongoing contribution to NATO's Resolute Support Mission, a small number of UK personnel have been deployed to Camp Shorabak in Helmand Province in an advisory role," a British spokesman said.
"In total the UK has around 450 troops in Afghanistan mentoring and supporting the Afghan National Defence and Security Forces and the Afghan Security Ministries."
Sangin district has been witness to a bloody past, especially for the UK, as it has lost almost a quarter of its troops deployed in Afghanistan in Sangin.
A statement from Taliban has already been issued as a threat, saying: "They [British] were defeated even after the presence of thousands of troops and the same will happen with these few hundred troops, this means nothing else but a shameful humiliation for them. They have made no accomplishment even after fighting for the past 14 years. We are still strong."
