WASHINGTON, Aug. 3 (Xinhua) -- U.S. defense chief met with his military advisors over the weekend to discuss the security situation in Afghanistan, said the Pentagon on Monday.

    Pentagon spokesman Geoff Morrell told a press conference that Secretary of Defense Robert Gates and Chairman of the Joint Chiefs of Staff Adm. Mike Mullen met with top American commanders in charge of the Afghanistan war at a U.S. air base in Belgium on Sunday.

    According to Morrell, they got an interim report from Gen. Stanley McChrystal, the U.S. chief commander in Afghanistan, on the assessment of the war, which will be officially released later this month.

    "He wanted an opportunity to speak first hand with his commanders and his senior military advisers about how the assessment is unfolding," said the spokesman of the defense secretary.

    "The secretary will get what he asked for, which is an assessment of the security situation on ground, whether the resources that have been provided are being used to maximum effect, and whether additional resources would be necessary to complete the mission that's been tasked," he added.

    Earlier U.S. media reports said that McChrystal is likely to suggest sending more resources and troops to the Afghanistan amid the increasing violence by Taliban and other militant groups.

    President Barack Obama has announced that the United States will deploy 21,000 more troops to the country earlier this year, bringing the total number to 68,000 scheduled to be in the country by the end of this year.
