Militants have killed three American soldiers and wounded 29 others in eastern Afghanistan, the US military has confirmed.

A US military commander in Afghanistan has confirmed that the soldiers were killed during a military operation in the eastern province of Kunar.

The death toll is expected to rise as some of the injured soldiers are said to be in critical condition.

At least 289 foreign soldiers have been killed in Afghanistan so far this year.

At least 2,570 US-led soldiers have been killed in Afghanistan since the US-led invasion of the country in 2001, according to icasualties.

The security situation remains fragile in Afghanistan despite the presence of at least 150,000 US-led foreign forces in the country.

The increasing number of troop casualties in Afghanistan has caused widespread anger in the US and other NATO member states, undermining public support for the Afghan war.
