Taliban fighters have seized control of a key district in western Afghanistan that includes an important border crossing with Iran, Afghan security officials said, adding the armed group continues its rapid military advances around the country.

In the last week, the Taliban overrun areas bordering five countries – Iran, Tajikistan, Turkmenistan, China and Pakistan – as foreign forces end their 20-year intervention and the domestic security situation deteriorates.
Pitched battles between Taliban fighters and Afghan government forces were also under way in the northern Balkh province bordering Uzbekistan.
Senior security officials said 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 interior ministry, denied the reports and said the border crossing was still under the control of government forces.
