US Secretary of State
Hillary Rodham Clinton Friday arrived in Islamabad on a brief visit to ease bilateral relations strained since the May 2 killing of Osama bin Laden in his Pakistani hideout by US special forces, DPA reported.
"She has arrived and she will stay in Pakistan only for five to six hours," a spokesman for Pakistan's Foreign Office said.
Clinton is to meet with President Asif Ali Zardari, Prime Minister Yousuf Raza Giilani and military chief General
Ashfaq Parvez Kayani.
She is accompanied by Admiral Michael Mullen, chairman of the US Joint Chiefs of Staff, who arrived in Islamabad late Thursday.
Relations have been strained following the US operation that killed al-Qaeda chief bin Laden in a compound in the north-western city of Abbottabad.
US officials have asked Pakistan to investigate whether some elements within its intelligence agencies were involved in providing shelter to bin Laden, who lived near a military academy in Abbottabad for five years.
Pakistan has dubbed the US special forces operation a violation of its sovereignty and has reduced the number of US military personnel, most of them trainers.
Some US lawmakers have demanded blocking the 7 billion dollars of annual financial aid for Pakistan if it does not show full commitment in the fight against terrorism.
