KABUL - Afghan President Hamid Karzai accused the United States on Sunday of breaching a pact to hand over the main US military prison at Bagram Airbase and its inmates to Afghan control, after meeting Washington's top envoy to the region.

In a row which could complicate already thorny negotiations over the future US military presence in the country, Karzai told US Special Envoy to Afghanistan and Pakistan Marc Grossman any delay to the handover was "a serious violation" of a strategic agreement between the allies.

"The people of Afghanistan consider the issue of prisons and detention of their fellow citizens a matter of their national sovereignty," said a statement released by Karzai's office after the president met Grossman at his garden palace in Kabul.
