Patna, Nov 8 (IANS): Bihar Chief Minister Nitish Kumar leaves Friday for a weeklong trip to Pakistan during which he hopes to visit Indus Valley Civilisation sites Harappa and Mohenjodaro, an official said.

Nitish Kumar, who will be visiting Islamabad, Karachi and Lahore during the goodwill visit, has left for New Delhi and will leave for Pakistan from there. He heads an 11 member delegation of ministers and officials in the Nov 9-16 visit, an official in the chief minister's office said.
