A 16-year-old girl was killed in firing by Pakistan on Friday along the Line of Control in the Saubjian area of Poonch district, about 250 km from Jammu city.
The firing began around 5pm and injured four others. Indian troops responded in a calibrated manner, said a defence spokesperson.
The cross-border shelling that injured six people on Thursday intensified after India beat Pakistan to win the hockey gold at the Asian Games.
Pakistan had consistently fired from mid July to August, a total of 45 days, along the international border. Since then, the guns had fallen silent but firing resumed Wednesday.
Late Friday, Pakistan also started firing in the Arina area of Jammu district, along the international border.
