ISLAMABAD - Defense Secretary Jim Mattis arrived in Pakistan Monday as Washington pressures its wayward ally to eliminate militant 'safe havens,' days after Pakistani authorities freed an alleged mastermind of the 2008 Mumbai attacks.
Mattis landed at an air force base in Rawalpindi, according to a pool report, before heading to the US embassy.
During the brief stopover in the capital, he is set to hold talks with Prime Minister Shahid Khaqan Abbasi and the military chief General Qamar Javed Bajwa.
Mattis's first visit to the country as defense secretary of defense comes as the US pushes its longtime ally to do more to combat insurgents who allegedly use bases in Pakistan's tribal belt to target NATO troops in Afghanistan.
Relations suffered a further blow after a Pakistani court ordered the release of firebrand cleric Hafiz Saeed in late November, prompting a furious response from the White House.
Saeed heads the UN-listed terrorist group Jamaat-ud-Dawa and has a $10 million US bounty on his head. He had been under house arrest but was released after a court in Lahore said officials had not provided any evidence of his role in the days-long assault on India's capital which killed more than 160 people.
The decision to release Saeed coincided with the beleaguered government's capitulation to Islamist protesters holding a sit-in in the Pakistani capital.
The deal, which the military helped broker, saw the federal law minister resign over blasphemy allegations.
It sent shockwaves through the country, sparking fears that the military was doing little to keep extremism in check after supporting the demands of a small group of hardliners.
President Donald Trump first signalled that the US was reassessing its fractious relations with Pakistan during a televised speech in August, launching a blistering attack on Islamabad for harbouring 'agents of chaos'.
The remarks triggered a series of high-level diplomatic meetings in the US and Pakistan, but Islamabad has given few signs of concessions to Washington.
