The United Nations Committee on the Rights of the Child on Wednesday also expressed deep concern at the arrest and detention of Afghan children by US-led forces.

According to the UN report, some of the children were abused in US detention facilities.

The report also said “those responsible for the killings have not been held to account even as the number of children killed doubled from 2010 to 2011.”

The committee has issued recommendations to Washington regarding US practices during armed conflicts, which are harmful to children.

The committee called on the US to take measures to prevent the killing and maiming of civilians and children.

Human Rights Watch has called on the US to promptly carry out the UN recommendations to improve the protection of children in the war-stricken country.
