Chairman of the US Senate Foreign Relations Committee, John Kerry has pressed Pakistan to take action against militant sanctuaries on its territory. He said the two countries had agreed on a series of steps to get their relationship back on track in the wake of the killing of Osama bin Laden in a covert US operation. Kerry, is the first senior American official to visit Pakistan since the Al Qaida chief was killed in Abbottabad on the 2nd of May. Following his meetings with President Asif Ali Zardari, Prime Minister Yousuf Raza Gilani and Army Chief Gen Ashfaq Parvez Kayani, Kerry said he had received assurances of cooperation and there is a need to flush the terrorists out.US Senator John Kerry says, he and Pakistani officials have agreed on steps to improve bilateral relations strained by the US raid that killed Osama bin-Laden in northern Pakistan earlier this month. At a meeting with President Asif Ali Zardari and Prime Minister Yusuf Reza Gilani in Islamabad, Kerry said the goal of his visit was not to apologise for the bin-Laden raid which he called a triumph against terrorism, but to try and repair US-Pakistan relations.Pakistan's Prime Minister Gilani warned last week that any future unilateral actions will carry serious consequences, while the US officials question how the Al Qaeda leader was able to live in Pakistan for years without being detected. There has been speculation that Pakistani leaders had actually helped bin Laden to find refuge in the country. Kerry said there was no proof of that but did warn of deepening US mistrust and anger with Pakistan.
