Suicide attacks targeting security personnel have killed at least three people in Afghanistan on Monday, according to officials. 

An attack on an Afghan National Army vehicle in front of a health clinic in the eastern province of Nangahar killed two people and wounded six others, according to police spokesman Hazrat Hussain Mashriqiwal.

It followed an earlier attack that killed an Afghan passer-by in Kabul, when a suicide bomber detonated a car full of explosives near a convoy of foreign soldiers, according to deputy interior minister Mohammad Ayob Salangi. 

Sergeant Ahamd Zubair, one of the police officers responding to the explosion in Kabul, said at least two American trainers and their Afghan driver were injured. He said another Afghan died of his injuries in hospital. 

The NATO-led International Security Assistance Force confirmed the attack, saying there are no reports of any of its troops being killed. 

The Taliban's purported spokesman Zabihullah Mujahid claimed responsibility for the Kabul attack, saying the attack targeted "invader forces" and damaged three vehicles.

It was the sixth suicide attack in Kabul since a new government was formed on September 29. The other attacks targeted Afghan national security forces rather than foreign troops. 

In a similar incident, three Afghan national army soldiers and three civilians were killed in a suicide car bomb attack on army convoy in Wardak province, 60 kilometers southeast of Kabul on Sunday.
