Russian news agencies are reporting that the leaders of India and Pakistan have met on the sidelines of a summit in Russia. State-run RIA-Novosti and Interfax say Indian Prime Minister Manmohan Singh and Pakistani President Asif Ali Zardari held a bilateral meeting Tuesday. It is the first interaction between the two leaders since the terrorist attacks in the Indian city of Mumbai last November. India accuses a Pakistan-based militant group of sending the teams of gunmen that rampaged through Mumbai in a three-day siege that left 166 people dead. Pakistani officials have acknowledged the November attacks were partly plotted on their soil.
