The White House says there would be repercussions for US-Pakistan relations unless Islamabad took action to detain and charge a newly freed Islamist accused of masterminding a 2008 assault in Mumbai, India.
A Pakistani court ordered the release on Wednesday of Hafiz Saeed, who was put under house arrest in January after years of living freely in Pakistan, one of the sore points in its fraying relationship with the US. His freedom had also infuriated its arch-foe India.
The White House on Saturday urged Pakistan to arrest Saeed, calling for him to be prosecuted over the Mumbai attack that killed 166 people, including Americans.
"If Pakistan does not take action to lawfully detain Saeed and charge him for his crimes, its inaction will have repercussions for bilateral relations and for Pakistan's global reputation," the White House said in a statement on Saturday.
This is the first time the US has acknowledged that the recent decision could have an impact on relations between the two countries, who are allies but view each other with suspicion.
Saeed has repeatedly denied involvement in the Mumbai attacks in which 10 gunmen attacked targets in India's largest city, including two luxury hotels, a Jewish centre and a train station in a rampage that lasted several days.
The violence brought nuclear-armed neighbours Pakistan and India to the brink of war.
The US had offered a $US10 million bounty for information leading to the arrest and conviction of Saeed, who heads the Jamaat-ud-Dawa (JuD). Members say the JuD is a charity but the US says it is a front for the Pakistan-based Lashkar-e-Taiba (LeT) militant group.
The White House said Pakistan's failure to charge Saeed sent a "a deeply troubling message about Pakistan's commitment to (combating) international terrorism". It added that it also was counter to Pakistan's claim that it did not provide sanctuary to militants.
