Darqad district in northern Afghanistan’s Takhar province fell to the Taliban around 4am (2330 GMT Tuesday), an official said, after a six-hour battle.
“The Taliban attacked the district centre from several sides and were able to take the district,” said Khalil Asif, a spokesman for Takhar provinical police.
He said there might be casualties from the attack.
“Twelve police and two Taliban were killed in the attack,” Taliban spokesman Zabiullah Mujahid said, “and two other Taliban Mujahid were wounded.”
Takhar is amongst Afghanistan’s most volatile provinces with several districts contested.
Afghan forces are stretched to the limit trying to battle the insurgency, while providing assistance to other government agencies that are busy helping the victims of this week’s earthquake.
