New Delhi, Aug 20 - US Ambassador to India Timothy J. Roemer Thursday met Home Minister P. Chidambaram and discussed among other issues anti-terror ties between the two countries.

Home ministry sources said cooperation in anti-terror measures was among various bilateral issues that figured at the meeting between Roemer and Chidambaram.

'It was a good meeting,' Roemer told reporters after the 35-minute closed door talks in the home minister's office at North Block here.

The meeting comes against the backdrop of the US government's valuable assistance to India in probing last year's Nov 26 terror attack in Mumbai.

The Federal Bureau of Investigation (FBI) helped in tracking the Global Positioning System (GPS) telephony used by the terrorists during the attacks and said the devices reflected the route from Karachi to Mumbai and also positions between these two cities.
