Taliban fighters with suicide bombs and heavy weaponry launched co-ordinated attacks on the embassy district and other parts of the Afghan capital, Kabul, late on Tuesday.
Intelligence services and a government ministry were being targeted, a Taliban spokesman said. But a BBC correspondent in the city said the targets appeared to be the US embassy and the headquarters of the Nato-led coalition, Isaf.
Afghan police and security services responded, but gun battles continued to rage in the city overnight.
Nato helicopters were also called in to target an unfinished high-rise building overlooking the diplomatic quarter, where the attackers had holed up.
In the western part of Kabul, at least two suicide bombers detonated their bombs targeting local police.
Several people were killed and more than a dozen injured in the attacks, officials said. A number of Afghan police officers were among the dead.
Much of Kabul was sealed off as the security operation continued.
The assault, the most complex insurgency attack in Kabul to date, finally came to an end after nearly 20 hours.
The attackers are thought to have carried a large amount of weapons and explosives into the building over several days.
Afghan security and intelligence officials have entered the building to search it for evidence, and to retrieve the bodies of the attackers.
The US ambassador to Afghanistan, Ryan Crocker, said he was encouraged by the "lack of ability" shown by the insurgents, and has praised the Afghan security forces for their handling of the attack.
