Afghan officials say a suicide blast early Monday in Kabul killed two intelligence officers and four civilians, while injuring two people.
The bombing occurred near a security check post on a busy road in the capital. The bomber apparently wanted to target Afghan security forces and instead hit a civilian car, said Najib Danish, an Interior Ministry spokesman.
The Islamic State group claimed responsibility for the blast through its Amaq news agency.
White House Press Secretary Sarah Sanders says President Donald Trump has been briefed on the attack.
Monday's bombing comes a week after Islamic State claimed an attack on a National Directorate of Security training facility in Kabul.
