Pakistan Prime Minister Yousuf Raza Gilani [ Images ] is unlikely to meet his Indian counterpart Dr. Manmohan Singh [ Images ] in Washington, where they are scheduled to attend the Nuclear Security Summit in Washington on April 12 and 13.

Pakistan Foreign Office (FO) spokesman Abdul Basit said he is unaware of any such meeting between the two leaders on the sidelines of the upcoming summit.

"I don't know yet," The Daily Times quoted Basit, as saying.

The focus of the conference hosted by President Barack Obama [ Images ] is on securing vulnerable nuclear materials and preventing acts of "nuclear terrorism".

The White House has invited 44 countries to the summit, though the list of delegates has not been finalised yet.
 
"The purpose of the summit is to discuss steps we can collectively take to secure vulnerable nuclear materials and prevent acts of nuclear terrorism," White House spokesman Robert Gibbs had said earlier.
