New Delhi-Jammu (PTI): Pakistani forces on Wednesday lobbed heavy 82 mm mortar shells at Indian positions across the Line of Control in Northern Kashmir, marking a major esclation just a day after India conveyed its strong concerns over mounting ceasefire violations.

Six mortar shells were fired at BSF positions in two bursts in a span of one hour from 1130 on wednesday morning in Nowgam sector of Baramulla district, just miles away from the border post which had wittnessed heavy exchange of fire on Tuesday.

The mortar shells fell just short of the Nerian post being manned by BSF personnel.

"There were no casualties on the Indian side", army sources said adding Indian troops did not retaliate to the shelling.

Local army commanders got in touch with their Pakistani counterparts to point the trangression and to get the troops to cease fire, sources said.

The firing comes even as India on Tuesday conveyed its concerns over several instances of cross-border firing by Pakistani troops along the 742 km. LOC.
