US Central Command said 1,300 pieces of equipment had been sent for destruction and one facility in the southern province of Helmand had been transfered to the Afghan army since President Joe Biden's April 14 announcement of the pullout.

The US military is to publish weekly updates on the withdrawal, including on "the retrograde of troops and equipment" and turning over equipment and facilities to the Afghan security forces.

Afghan troops have faced increased insurgent attacks in recent days in Helmand, where the United States on Sunday handed over the Antonik base as part of its formal pullout that began on May 1.

The US has downplayed the latest fighting and said the withdrawal process was unaffected as it removes its final 2,500 troops from the country.

US military leaders have raised fears that the Kabul government could fall to the Taliban after the pullout, and say the insurgents now control more Afghan territory than 10 years ago.
