Defence Minister A K Antony on Friday said the truce between Pakistan and Taliban has added to India's "worries" over the security situation in the region. "From 26/11 onwards, we are very much concerned about the security scenario. This new development, in a way, adds to our worries," Antony said when asked to comment on the ceasefire between Pakistani troops and Taliban militia in the Swat valley, under which Islamabad has virtually surrendered to the demands of the fundamentalists. Antony said the Government's stand on the issue was already cleared by External Affairs Minister Pranab Mukherjee. "On behalf of the Government, External Affairs Minister has already reacted. What he has said is the posture of the Government," he said on the sidelines of an award ceremony for best marching contingents at this year's Republic Day parade.
