Pakistan and India on Wednesday agreed to boost cooperation between their civilian investigation agencies to control terrorist activities, illegal immigration, influx of fake currency and liberalise the visa regime under a joint anti-terrorism mechanism. Officials of the interior ministry said the decisions were taken during the composite dialogue, which reviewed proposals by President Asif Ali Zardari for a treaty to make South Asia a non-nuclear region and an economic hub. It was the fifth round of home secretary-level talks. The Indian side was represented by Union Home Secretary Madhukar Gupta and Interior Secretary Syed Kamal Shah represented Pakistan.
