Sites in Pashto, Urdu, Arabic, English and Dari languages went offline on Friday.
They had been shielded by Cloudflare, a San Francisco-based content delivery network and denial-of-service protection provider.
It was not immediately clear, however, why the sites went offline. The websites’ disappearance may merely be temporary as the Taliban secures new hosting arrangements.
But the reported removal of the WhatsApp groups followed the banning of Taliban accounts by Facebook, the service’s parent company, on Tuesday after the US-backed Afghan government fell to the Taliban.
The company indicated on Tuesday that as long as such accounts observed its rules — including not inciting or glorifying violence — they would remain active.
The Taliban is not on the US list of foreign terrorist organisations, but the US has imposed sanctions against it.
Twitter has not removed Taliban accounts and the group’s spokesman, Zabihullah Mujahid, has more than 300,000 followers there.
