Assistant Secretary of State for Public Affairs, P J Crowley was responding to a query when asked about the statement by Indian Home Secretary G K Pillai that India would seek extradition of Headley.
Speaking to reporters, Crowley said, "Obviously, we do have an extradition treaty with India, but how that will work going forward, I think that's premature"
Early this week, FBI formally charge sheeted US terror suspect David Coleman Headley for being allegedly involved in the Mumbai terrorist attacks.
Union Home Secretary Pillai had said that once India completes its probe into Headley's links with the Mumbai terror attacks, the government will seek his extradition.
"Once we file the charge sheet, we will definitely be seeking access for both interrogation and at a subsequent stage, definitely his extradition," he said.
