(MENAFN- Arab News) KUNDUZ: Taleban insurgents advancing on the capital of a northern Afghan province have captured a key adjoining district officials said Sunday sparking renewed alarm among residents who fear the fall of the besieged city.

The Taleban launched their annual summer offensive in late April with a brazen assault in Kunduz province coming close to overrunning the provincial capital and sending civilian casualties soaring in outlying districts.
The capture of the worst-affected Chardarah district at the edge of Kunduz city on Saturday reignited concerns over its potential fall as insurgents escalate their annual summer offensive.
'The district has fallen to Taleban after hours of fierce fighting. Twelve Afghan forces have lost their lives and 17 have been wounded' Chardarah district chief Mohammad Yousuf Ayubi told AFP.
The militants are now as close as three kilometres to Kunduz city increasingly hemmed in by the insurgency with sporadic fighting still ongoing between the Taleban and pro-government forces.
The fall of a provincial capital would be a major setback for the Afghan government which has been fighting a resilient Taleban insurgency since the 2001 US-led invasion of Afghanistan. Deputy Afghan army chief General Murad Ali Murad said at least 70 security forces were surrounded by Taleban insurgents in Chardarah.
'We are going to start a military operation to retake the district on Sunday evening' he told AFP.
Abdul Sabor Nasrati the police chief of the province on the border with Tajikistan said the government was rushing reinforcements to Chardarah.
Civilians are bearing the brunt of a large-scale insurgent offensive in Kunduz the keystone of the Taleban's summer fighting season which is expected to be the bloodiest in a decade.
The province is facing a humanitarian crisis with thousands of families trapped in a vortex of violence as militancy spreads across the north beyond traditional Taleban hotbeds in the south and east.
