Taliban to announce formation of new government on Friday: Reports

The source added, on condition of anonymity, that it is not yet known who will be part of the government and what will be its format.

Meanwhile, the US Embassy in Kabul has suspended operations in Afghanistan and the last batch of American soldiers have left Kabul marking the end of the western country's mission in the South Asian nation.

"While the U.S. government has withdrawn its personnel from Kabul, we will continue to assist U.S. citizens and their families in Afghanistan from Doha, Qatar," the US Embassy said in a statement on Tuesday.

As the last US military flight carrying troops left the Hamid Karzai International Airport (HKIA) in Kabul, the United States completed the withdrawal of its forces from Afghanistan, ending a two-decade-long war ignominiously with Taliban in control.

The last three US military evacuation flights departed HKIA just ahead of the August 31 deadline. The last one, a C-17 Globemaster transport plane, took off from the Kabul airport at 3:29 pm. East Coast Time, Russia Today (RT) reported quoting General Kenneth McKenzie, head of the US Central Command (CENTCOM).

Foreign correspondents in Kabul reported how Taliban fighters rejoiced at the historic event with celebratory gunfire after the American withdrawal from Afghanistan was officially completed.
