The United States and Pakistan close to finding a solution to Islamabad’s ban on its crucial supply line to Afghanistan, the White House said .

“We are in discussions and working with the government of Pakistan to address the concerns relating to the closure of the border there. We believe we are close to producing some results on that and may have more on that in the future,” the White House Press Secretary, Robert Gibbs, said on Tuesday.

The discussions in this regard are happening at the Foggy Bottom headquarters of the State Department between the diplomats of the two countries.

He said. “We’re working government to government. We have expressed our condolences for what happened several days ago in Pakistan with ISAF and their forces. We’re working through the border closing right now,” Gibbs said.

Pakistan blocked a land route for NATO convoys carrying supplies to Afghanistan since Thursday after officials blamed a cross-border NATO helicopter attack for the deaths of three Pakistani soldiers.
