The Pakistan government has asked United States to cut down the number of military trainers that the US has stationed in Pakistan, the Pentagon said on Wednesday, reported Reuters.

The flimsy US-Pakistan relationship takes a bad turn further with the distrust growing after Osama Bin Laden killing by the US military force on May 2.

Pentagon spokesman Colonel Dave Lapan said the Pakistan government informed the United States in the last week or two that it would not need some of the U.S. trainers who are stationed in Pakistan to advise the Pakistani military. This would reduce the size of the overall U.S. military mission in Pakistan by a small number of people, he said, according to the report.

The entire military mission has between 200 to 300 people and there had been no real change to the small US military training mission in Pakistan, he added.

This reduction comes after weeks of the US government carrying out its secret mission of killing the Al-Qaeda leader at his compound near Islamabad, which Pakistan clearly sees as a violation of its sovereignty. This raised suspicions about Pakistan's role in sheltering militants and also weakened US-Pakistan relationship.

Over the past 10 years, US has sanctioned about $20 billion to Pakistan for military reimbursements and to help fight its extremists. with the Bin laden killing, lawmakers are urging Obama to reconsider assistance to Pakistan, the report stated.
