The shooting occured in the Battal sector of Pakistan-controlled Kashmir, known as Azad Kashmir on Monday, Mar 1, Pakistan said.
"An innocent boy and a girl were seriously injured due to unprovoked firing by Indian troops across the Line of Control," a military official said, referring to the line dividing the Pakistani and Indian portions of the Himalayan region.
"Pakistani troops responded effectively," he said without giving details.
The incident adds to a list of the cross border firings which has been on the upsurge in the past few months.
On Feb 25, the foreign secretary level talk was resumed between the two countries after India decided to suspend talks with its neighbour following the Mumbai terror attacks in Nov 2008.
However, while hopes were high on positive outcome of the talks, there seems to be no significant changes as both the sides failed to arrive on an agreement against terrorism and Kashmir issue.
At the end of the talk both the parties agreed to keep in touch but India refused to resume composite dialogue.
