Taliban fighters overran a district center in Zabul and destroyed and looted several bases, including one along a main highway. Afghan officials previously downplayed the fighting in Zabul.
Mizan district was under siege for more than one year before it fell. Security in Zabul province, which is a known haven for al Qaeda and straddles the border with Pakistan, has deteriorated over the past five years. Al Qaeda operated a base in Mizan as recently as Sept. 2016.
