US and NATO forces in Afghanistan will withdraw ground forces from the country by May 1 and aim to complete the pullout of all assets by September 11.
"[Austin] has approved some additional measures today, he has approved the extension of USS Eisenhower to remain in the Central Command area of responsibility for a period of time and he has approved the addition of some long-range bombers to be deployed to the region," Kirby said in a press briefing. "Two of those B-52s have arrived in the region."
Kirby said it is possible there can be a temporary increase of US ground forces in Afghanistan to assist in an orderly withdrawal.
US media reported earlier on Friday that the United States is already starting to remove military equipment from Afghanistan. Kirby confirmed the report, adding that equipment will be brought to the United States, deployed to other regions in the world, transferred to the Afghan security forces, or destroyed.
Kirby added that all military equipment will be shipped out of Afghanistan by air but he does not have a current estimate of how much the US withdrawal operation will cost.
Afghanistan continues to see clashes between Taliban insurgents and the Afghan military, despite the launch of peace talks between the movement and Kabul in Qatar's Doha in September 2020.
US Central Command (CENTCOM) Commander Kenneth McKenzie said on Thursday that intra-Afghan peace talks currently appear to be in a short-term deadlock and emphasized the need for the United States to continue supporting the Afghan government to prevent it's collapse after the foreign forces withdraw.
