As many as five rockets were fired at the Kabul airport but were intercepted by a missile defense system on Monday, news agency Reuters reported quoting an American official.
The rockets were fired a day after the US carried out an airstrike in the Afghan capital on an explosives-laden vehicle, the report said.
Quoting the official, the report said rockets were fired early Monday morning Kabul time, though it was unclear if all were brought down by the defence system. This came even as the United States nears the complete withdrawal of its troops from the city.
The official also told Reuters that initial reports did not indicate any US casualties but that information could change.
The report quoting AFP journalists said they could hear the sound of rockets flying across the city even as the United States raced to complete its withdrawal from Afghanistan, with the evacuation of civilians all but over, amid fears of attacks.
People living near the airport said they heard the sounds of the missile defence system being activated and smoke could be seen rising near the airport, AFP reported.
On Saturday, US President Joe Biden said the situation on the ground remained extremely dangerous, and that his military chiefs had told him another militant attack was highly likely within the next 24-36 hours.
