Afghan forces scrambled Thursday to beat back the Taliban from Sangin as the insurgents claimed to have captured nearly the entire opium-rich district, following the first British deployment to the volatile region in 14 months.
The Islamists broke through the frontlines of Sangin on Sunday after days of pitched clashes with besieged Afghan forces, tightening their grip on the southern province of Helmand.
Fleeing residents reported Taliban executions of captured soldiers as the insurgents advanced on the district centre, compounding fears that the entire province was on the brink of a security collapse.
Government officials Thursday denied reports that Sangin was on the brink of falling to the Taliban, saying that reinforcements were trying to relieve dozens of security forces holed up in the district centre.
"Afghan army commandoes and police forces have launched an operation in Sangin," said interior ministry spokesman Sediq Sediqqi, claiming heavy Taliban losses.
But Taliban spokesman Zabiullah Mujahid claimed insurgents had overrun the entire district, pinning down Afghan forces in a military base where trapped soldiers reported dire conditions.
"Our men are hungry and thirsty," Abdul Wahab, a local police commander in Sangin, told AFP.
"Stepping out to get bread means inviting death," he said, adding that dozens of his comrades had been killed and grievously wounded.
The war in Helmand, seen as the epicentre of the expanding insurgency, follows a string of military victories for the Taliban after NATO formally ended its combat operations last year.
All but two of Helmand's 14 districts are effectively controlled or heavily contested by the Taliban, who also recently came close to overrunning the provincial capital Lashkar Gah.
The turmoil in Helmand, the deadliest province for British and US forces in Afghanistan over the past decade, underscores a rapidly unravelling security situation in Afghanistan.
Britain on Tuesday said a small contingent of its troops had arrived in Camp Shorabak, the largest British base in Afghanistan before it was handed over to Afghan forces last year.
The deployment, in addition to a recent arrival of US special forces in the region, is the first since British troops ended their combat mission in Helmand in October 2014.
The contingent, which an Afghan official said includes around 90 people, is on an "advisory" mission with London insisting they will not engage in combat.
Expanding war
The Taliban on Wednesday slammed the British deployment after last year's pullout as "a sign of stupidity" and threatened to target the "newly arrived invaders".
The intervention has fuelled the perception that foreign forces are increasingly being drawn back into the conflict as NATO-trained Afghan forces struggle to rein in the Taliban.
The unrest in Helmand, blighted by a huge opium harvest that helps fund the insurgency, comes after the Taliban briefly captured Kunduz city in September — their biggest victory in 14 years of war.
President Barack Obama in October announced that thousands of US troops would remain in Afghanistan past 2016, acknowledging that Afghan forces are not ready to stand alone.
The latest unrest in Helmand comes after President Ashraf Ghani made a diplomatic outreach to Pakistan — the Taliban's historic backers — aimed at restarting peace talks with the insurgents.
Pakistan hosted a first round of negotiations in July but the talks stalled when the Taliban belatedly confirmed the death of longtime leader Mullah Omar.
A security official in Islamabad told AFP Tuesday that Pakistan army chief Raheel Sharif would travel to Kabul in the coming days, in what appears to be a renewed push to jumpstart talks.
Afghanistan's spy agency chief resigned this month after a scathing Facebook post that vented frustration over Ghani's diplomatic outreach to Pakistan.
Rahmatullah Nabil's resignation raised uncomfortable questions about a brewing leadership crisis in Afghanistan as the insurgency gains new momentum.
