Taliban insurgents captured a key district just outside the Afghan capital Kabul in central Maidan Wardak province on Tuesday, forcing government forces to retreat, security officials have confirmed.

The capture of Nerkh district comes amid intensifying violence across the country following an announcement by the Taliban of a three-day ceasefire over Eid-ul Fitr.

Reuters reported that Tariq Arian, an interior ministry spokesman, said government troops made a “tactical retreat” from the district centre, which is a gateway to Kabul, after a heavy firefight with the Taliban.

Zabihullah Mujahid, a Taliban spokesman, wrote on Twitter that they had killed and captured some members of the Afghan security forces after seizing the district. He added that they had also seized a large cache of ammunition.

The Afghan government did not comment on casualties among the security forces.

The Taliban have dug in, in Wardak, which lies less than an hour’s drive west of Kabul, and in nearby Logar province to the south.

Afghan officials say the Taliban have used the provinces – gateways to the capital – as launchpads for hit-and-run attacks and suicide bombings on Kabul, Reuters reported.

Abdul Rahman Tariq, Maidan Wardak’s governor confirmed the fall of the district to Ariana News.

“Unfortunately, as a result of a compromise, the Taliban took control of the district yesterday and the security forces made a tactical retreat,” he said.

Deputy spokesman for the Ministry of Defense, Fawad Aman tweeted Wednesday that Afghan commando forces have arrived in Maidan Wardak province.

“Nirkh district will become a Taliban cemetery,” Aman tweeted.
