EU foreign policy chief Josep Borrell says it's "mathematically impossible" for the US and its allies to evacuate tens of thousands by August 31. The US military is currently in control of Kabul's airport and running its air traffic control operations. Borrell denies there are tensions between the European Union and the over the ongoing evacuations. August 31 is the deadline the United States had announced for the complete pullout of its forces from Afghanistan, but President Joe Biden has flagged that might be extended if airlifts remain viable.
