Officials say two siblings and their mother have been killed in cross-border shelling between Indian and Pakistani soldiers in disputed Kashmir.

Indian police say the three died overnight after a shell fired by Pakistani soldiers hit their home in Poonch region near the so-called Line of Control that divides the Himalayan territory of Kashmir between the two nuclear-armed rivals.

Indian army says its soldiers responded.

Tensions have been running high since Indian aircraft crossed into Pakistan on Tuesday, carrying out what India called a pre-emptive strike against militants blamed for a Feb. 14 suicide bombing in Indian-controlled Kashmir that killed 40 Indian troops.

Pakistan retaliated, shooting down a MiG-21 fighter jet Wednesday and its pilot, who was returned to India on Friday in a peace gesture.
