The US has asked Pakistan to take "sustained and irreversible" actions against terrorist groups operating from its territory and areas under its occupation, according to a top State Department official.
The US State Department statement came as Pakistan, under global pressure after the Pulwama terror attack and India's subsequent air strikes against a Jaish-e-Mohammed terrorist camp in Balakot on February 26, has reportedly started taking actions against some of the terrorist outfits and their heads over the past few days.
In Islamabad, the Interior Ministry announced that a total of 121 members of the proscribed terror groups have so far been taken into "preventive detention" across Pakistan.
US State Department Deputy Spokesperson Robert Palladino told reporters at his bi-weekly news conference on Thursday, "I would say that we, the United States notes these steps and we continue to urge Pakistan to take sustained, irreversible actions against terrorist groups that will prevent future attacks and promote regional stability".
"We reiterate our call for Pakistan to abide by its United Nations Security Council obligations to deny terrorists safe haven and block their entry to funds," he said.
Responding to questions, Mr Palladino refrained from giving a direct answer on the move in New York to designate Jaish-e-Mohammed or JeM chief Masood Azhar as a global terrorist, but said that the US and its allies in the UN Security Council want to update the UN list of terrorist organisations and leaders.
"Our views on Masood Azhar and Jaish-e-Mohammed are well-known. Jaish-e-Mohammed is a United Nations-designated terrorist group that has been responsible for numerous terrorist attacks and is a threat to regional stability. Masood Azhar is the founder and leader of JEM," he said.
Questions on United Nations sanctions committee deliberations are confidential and as such it is not something that the State Department is going to be able to comment on specific matters in that regard, he said.
"But we will continue to work with the sanctions committee to ensure that the list is updated and that it is accurate," Mr Palladino said.
At the US Capitol, India's ambassador to the US Harsh Vardhan Shringla met Kevin McCarthy, the Republican leader in the House of Representatives.
"We must stand strong against acts of terrorism and work together to improve trade between our nations," the top Republican leader said after the meeting.
Tensions between India and Pakistan flared up after a suicide bomber of Pakistan-based terror group Jaish-e-Mohammed or JeM exploded over 60 kg of RDX near a CRPF bus, killing more than 40 soldiers in Jammu and Kashmir's Pulwama district on February 14.
India launched a "non-military, pre-emptive" counter-terror operation in Pakistan's Balakot on February 26. The next day, Pakistan Air Force retaliated and downed a MiG-21 fighter jet of the Indian Air Force, while losing an F-16 jet of their own. Pakistan also detained the MiG-21 pilot Wing Commander Abhinandan Varthaman, who was handed over to India on Friday.
