Pakistani Prime Minister Yousuf Raza Gilani is planning to go before lawmakers to outline the government's response to last week's NATO attack that killed 24 Pakistani troops along the Afghan border.

The prime minister says he will brief the parliamentary committee on national security Friday. The committee is already reviewing Pakistan's future relationship and cooperation with the United States and NATO following last Saturday's attack.

In response to the deadly coalition strike, Pakistan has shut down NATO's Pakistani supply routes into Afghanistan and decided to boycott next week's international conference on Afghanistan in Bonn, Germany.

On Wednesday, Prime Minister Gilani told German Chancellor Angela Merkel that the national security committee would decide whether Pakistan's ambassador to Germany would represent the South Asian country at the Bonn conference. Chancellor Merkel joined other world leaders in urging Pakistani leaders to attend the summit.

Meanwhile, the U.S. Embassy in Islamabad on Thursday released a video message of U.S. Ambassador Cameron Munter expressing condolences for the November 26 deaths of the Pakistani soldiers in the Mohmand tribal area.

Munter added in Urdu that “we regret it very much.”

NATO and U.S. Central Command are investigating the circumstances that led to NATO's bombing of two Pakistani military posts along the Afghan border.
