US Defence Secretary James Mattis today reached Pakistan with the issue of terrorist safe havens high on the agenda, after the release from house arrest of 26/11 mastermind Hafiz Saeed last month. <br/><br/>He will hold talks with civilian and military leaders including Pakistan Prime Minister Shahid Khaqan Abbasi and Army Chief General Qamar Javed Bajwa. <br/><br/>Relations between the US and Pakistan have plummeted after President Donald Trump announced his new Afghan and South Asia policy in August and directly blamed Islamabad for supporting the Afghan Taliban. <br/><br/>Mr Mattis is on a five-day tour to Egypt, Jordan, Kuwait and Pakistan.<br/><br/>He is visiting Islamabad about a week after the White House asked Pakistan to immediately charge and arrest 26/11 Mumbai terror attacks mastermind Saeed, in the absence of which it warned of repercussions. <br/><br/>JuD chief Saeed, who has an American bounty of 10 million US dollar on his head, walked free on November 24 after a court ordered an end to his 10-month detention.<br/><br/>The Pakistan government decided against detaining him further in any other case, pushing back against India's efforts to bring the perpetrators of the 2008 Mumbai terror attack to justice. <br/><br/>Mr Mattis is the first top American official to visit Pakistan after the completion of the first 100 days of the US' new South Asia strategy unveiled by Trump on August 21.
