Washington, Dec 31 (Agencies): Pakistan has made only limited progress in improving human rights with reports of thousands of disappearances despite US pressure on its wartime partner, the State Department says.

In a report mandated by Congress, the State Department assured lawmakers that the United States was vetting forces' human rights as it extends billions of dollars to the frontline nation in the battle against extremism.

In October, President Barack Obama's administration said for the first time that it had cut off training to several units after a graphic video emerged that appeared to show summary executions.

The State Department, in the report completed in late November, said that Pakistan "has made limited progress in advancing human rights and continues to face human rights challenges."

"The State Department continues to press military and civilian authorities in Pakistan, at the highest levels, to take serious and sustained action to eliminate extrajudicial killings, provide humanitarian access and investigate all cases of disappearances," it said.

Earlier this month, Human Rights Watch said that at least 22 teachers and other education professionals were killed by suspected militants in Baluchistan between January 2008 and October 2010.
