New Delhi (PTI): The US Under Secretary of State William Burns on Wednesday held talks with Foreign Secretary Shivshankar Menon during which the latter is understood to have conveyed India's disappointment over Pakistan's inaction against perpetrators of Mumbai terror attacks.

During the detailed discussions covering bilateral and regional issues, the two sides are believed to have deliberated on the possibility of resumption of Indo-Pak dialogue that has been stalled since Mumbai attacks.

Menon is believed to have told Burns that India is not averse to resuming dialogue with Pakistan but for that a proper atmosphere will have to be created by Islamabad.

The Foreign Secretary is understood to have emphasised that talks cannot happen in an atmosphere of violence and lingering fears of terror attacks emanating from Pakistan.

Menon is also believed to have told Burns that India is disappointed with Pakistan's inaction against those behind the Mumbai attacks, which is highlighted by the release of Jamaat-ud-Dawa chief Hafiz Saeed.

Ahead of Burns's visit, State Department spokesman Ian Kelly said in Washington, "We would support more dialogue between the two countries.. I am sure that Under Secretary Burns will talk about this issue among the many issues that he has on his agenda."
