New Delhi, Sep 6 - Indo-US collaboration against the use of Pakistani soil for cross-border terrorism will be topmost on the agenda of Home Minister P. Chidambaram during his four-day visit to Washington and New York beginning Monday.

Home ministry officials said Chidambaram will meet Secretary of State Hillary Clinton, Interior Secretary Ken Salazar and National Security Advisor James Jones besides key officials of US intelligence and law enforcement agencies.

This will be Chidambaram's second foreign trip after taking over as home minister last December. Last month, he went to Bhutan.

He had to cancel his proposed January visit to the US after the 26/11 terror strikes and then to handle the situation arising out of the agitation by truck operators and officers of oil companies.

Officials here said that with the gunning down of Lashkar-e-Taiba (LeT) operative Abu Jindal by the Jammu and Kashmir police Friday, the home ministry was armed with fresh evidence against the Pakistan-based terrorist outfit.
