'Serious concerns have piled up in Indo-Pak ties'
India on Thursday said ``serious concerns'' have ``piled up'' in Indo-Pak ties in the backdrop of recent incidents, including killing of an Indian prisoner, which Pakistan will have to address before the two countries pick up ``strands'' of the composite dialogue.
India and Pakistan are planning to resume bilateral cricket ties after a nearly five-year disruption of such relationships due to the deadly Mumbai terrorist attacks in 2008, which were blamed on a Pakistani-based militant group.
