Taliban fighters yesterday seized control of a key district in western Afghanistan that includes a major border crossing with Iran, Reuters reported Afghan security officials saying.
In the last week, the Taliban have overrun areas bordering five countries – Iran, Tajikistan, Turkmenistan, China and Pakistan – as foreign forces end their two-decade intervention and the domestic security situation deteriorates.
Pitched battles between Taliban fighters and Afghan government forces were also underway in the northern Balkh province bordering Uzbekistan.
Two senior security officials told Reuters on condition of anonymity that the Islam Qala border crossing with Iran, located in Herat province, had fallen to the Taliban and that Afghan security and customs officials had fled across the border.
Al Alalam TV, Iran's official Arabic language service, also reported that Afghan soldiers had entered Iranian territory via the border crossing to escape the Taliban.
Tariq Arian, spokesman for the Afghan Ministry of the Interior, denied the reports and said the border crossing was still under the control of government forces.
Calls by Reuters to the offices of the provincial governor and police went unanswered.
Another security official said Taliban fighters had seized five districts in Herat without a fight.
Earlier this week, more than 1,000 Afghan security personnel fled into Tajikistan as the Taliban captured most of the northern province of Badakhshan, which also borders China and Pakistan.
The defence ministry said Afghan government forces earlier on Thursday wrestled back control of Qala-e-Naw, capital of the western province of Badghis, which had been stormed by the Taliban on Wednesday.
Hundreds of troops were deployed to the region, the ministry said, adding that fighting was continuing on the fringes of Qala-e-Naw, where insurgents had earlier seized key government buildings in the city including police headquarters.
"The city is fully [back] under our control and we are conducting operations against the Taliban on the outskirts of the city," Defence Ministry spokesman Fawad Aman said.
The ministry said 69 Taliban fighters were killed in operations on the edge of Qala-e-Naw – the first major provincial capital entered by the insurgents in their latest offensive.
The rest of Badghis province is in Taliban hands. Western security officials say the Taliban have captured more than 100 districts in Afghanistan.
Taliban official Shahabuddin Delawar said in Moscow today that the group now controls 85% of territory in Afghanistan.
