A bomb has exploded under a bridge in Afghanistan's capital, killing one person and wounding nine others.

The Interior Ministry said five police officers, including a district police chief, have been suspended over the March 29 blast in Kabul and are under investigation for neglecting their duties.

No one has claimed responsibility for the blast.

Roadside bombings are a major threat for both security forces and civilians across Afghanistan, where the Taliban have been waging a 15-year war against the government and foreign troops.

Afghanistan's police are widely seen as incapable and corrupt and are often implicated in crimes such as kidnapping for ransom.
