The top official also encouraged Pakistan and India to engage in talks to reduce tensions.
"The US is very aware of India's position (that talks and terror cannot go together) and we have called on Pakistan to crackdown on terror organisations like Lashkar-e-Taiba (LeT), Jaish-e-Mohammed (JeM) and others," the official told news agency PTI on a condition of anonymity.
"We have called Pakistan to take actions against those involved in the Mumbai terror attack, the Pathankot terror attack and other such attacks. So, the United States is very clear about its position," the senior administration official told reporters during a conference call.
The official made the remarks while responding to a question on India's stand that talks and terror cannot go together in the context of the Trump administration's South Asia policy that seeks a direct dialogue between India and Pakistan to reduce tensions.
"Pakistan needs to crackdown on terror groups," the US official said.
"And we are working with India to improve its counter terrorism. I think there is a lot of understanding between US and India on this issue," the official said in response to a question.
Earlier this month, External Affairs Minister Sushma Swaraj had told Parliament that the Indian government had laid the "roadmap" envisioning peace and normalcy with Pakistan even before it took over. "But it can't be one-sided...Terror and talks cannot go together. The day they stop promoting terror, we will start the talks," she had said.
The State Department on Wednesday had also asked the two countries to engage in talks.
"I think one of the things that we would do is ask or encourage India and Pakistan to sit down together and engage in direct dialogue that is aimed at reducing tensions between both of those countries," State Department Spokesperson Heather Nauert had told reporters.
