'We are ascertaining if any more rockets were fired. We retaliated with machine gun fire,' the IG said.

The BSF cordoned off the area and retaliated with machine-gun fire into Pakistan.

Later, commandants of the BSF and Pakistan Rangers held a meeting at the border in the wee hours of Saturday to investigate the incident. The Indian side lodged a strong protest over repeated incidents of shelling from across the border.

This is the second incident of rockets being fired into Indian territory from Pakistani soil. Earlier, three rockets were fired into Indian territory in early July.
